H0: Protype design has at most 37mpg vs. HA: prototype design has greater than 37mpg. If H0 is rejected, the action will be move the protype deisgn to prpduction. What kind of test is required
Answer:
A one-tailed test with upper reject region
Explanation:
H0 : μ ≤ 37
H1 : μ > 37
This is a right tailed tailed test as indicated by the greater than symbol on the hypothesis defined. Hence, the critical region will lie to the right of the area under the curve.
Critical region which lies to the right of the curve is called the upper rejection region.
Rejecting the Null, H0 means that ; the value of the test statistic exceeds the critical value;
When the hypothesis is declared with the less than sign, rejection region lies to the left or lower region.
While a two tailed test has rejection region shares between each tail.
The Marietta Country Club has asked you to write a program to gather, then display the results of the golf tournament played at the end of March. The Club president Mr. Martin has asked you to write two programs.
The first program will input each player's first name, last name, handicap and golf score and then save these records in a file named golf.txt (each record will have a field for the first name, last name, handicap and golf score).
The second program will read the records from the golf.txt file and display them with appropriate headings above the data being displayed.
If the score is = Par, then display 'Made Par'
If the score is < Par, then display 'Under Par'
If the score is > Par, then display 'Over Par'
There are 16 players in the tournament. Par for the course is 80. The data is as follows:
Andrew Marks 11.2 72
Betty Franks 12.8 89
Connie William 14.6 92
Donny Ventura 9.9 78
Ernie Turner 10.1 81
Fred Smythe 8.1 75
Greg Tucker 7.2 72
Henry Zebulon 8.3 83
Ian Fleming 4.2 72
Jan Holden 7.7 84
Kit Possum 7.9 79
Landy Bern 10.3 93
Mona Docker 11.3 98
Kevin Niles 7.1 80
Pam Stiles 10.9 87
Russ Hunt 5.6 73
Answer:
Explanation:
The following program is written in Python. It creates two functions, one for writting the players and their scores to the file, and another function for reading the file and outputting whether or not they made Par. The functions can be called as many times that you want and the writeFile function allows for 16 inputs to be made when called. A test case has been provided with all of the players mentioned in the question. The output can be seen in the attached image below.
def writeFile():
file = open('output.txt', 'w')
for x in range(16):
firstName = input("Enter First Name:")
lastName = input("Enter Last Name:")
handicap = input("Handicap:")
score = input("Score:")
file.write(str(firstName) + " " + str(lastName) + " " + str(handicap) + " " + str(score) + "\n")
file.close()
def readFile():
file = open('output.txt', 'r')
for line in file:
lineArray = line.split(" ")
if int(lineArray[-1]) < 80:
print(str(lineArray[0]) + " " + str(lineArray[1]) + " Under Par" )
elif int(lineArray[-1]) == 80:
print(str(lineArray[0]) + " " + str(lineArray[1]) + " Made Par")
else:
print(str(lineArray[0]) + " " + str(lineArray[1]) + " Over Par")
file.close()
writeFile()

Explanation:
Which tool, first introduced in Windows Server 2008 but remains in Windows Server 2019, provides one location to set up, deploy, and manage servers and server roles
Answer:
Server Manager
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM, Windows Server 2008, Windows Server 2009, etc.
Windows Server 2008 is a Microsoft Windows Server operating system and released to the general public on the 27th of February, 2008, as part of the Windows NT family.
Server Manager is a tool that was first introduced in Windows Server 2008 (OS) but remains in Windows Server 2019 (OS). It was designed and developed by Microsoft to provide end users with one location to set up, deploy, and manage servers and server roles.
On the 14th of January, 2020, Microsoft stopped providing online technical content update, free support options, non-security and free security updates on-premises for Windows Server 2008 and Windows Server 2008 R2, as they have reached the end of their support lifecycle.
11.11 LAB: Number pattern Write a recursive function called PrintNumPattern() to output the following number pattern. Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until 0 or a negative value is reached, and then continually add the second integer until the first integer is again reached. For this lab, do not end output with a newline. Ex. If the input is:
Answer:
The function in C++ is as follows:
int itr, kount;
void printNumPattern(int num1,int num2){
if (num1 > 0 && itr == 0) {
cout<<num1<<" ";
kount++;
printNumPattern(num1 - num2, num2);
} else {
itr = 1;
if (kount >= 0) {
cout<<num1<<" ";
kount--;
if (kount < 0) {
exit(0);}
printNumPattern(num1 + num2, num2);}}
}
Explanation:
We start by declaring global variables itr and kount
int itr, kount;
The function is defined here
void printNumPattern(int num1,int num2){
If num1 and itr are greater than 0 , then
if (num1 > 0 && itr == 0) {
Output num1, followed by a space
cout<<num1<<" ";
Increment counter by 1
kount++;
Call the recursion
printNumPattern(num1 - num2, num2);
If otherwise
} else {
Set itr to 1
itr = 1;
If counter is 0 or positive
if (kount >= 0) {
Output num1, followed by a space
cout<<num1<<" ";
Decrease counter by 1
kount--;
If counter is negative
if (kount < 0) {
Exit function
exit(0);}
Call the recursion
printNumPattern(num1 + num2, num2);}}
}
Answer:
void PrintNumPattern(int start, int delta) {
cout << start << " ";
if (start > 0) {
PrintNumPattern(start - delta, delta);
cout << start << " ";
}
}
void main()
{
PrintNumPattern(12, 3);
}
Explanation:
Looking at the "palindrome" symmetry of the output, you want one nesting level of the function to print the output twice. Then you also don't need global variables.

In cell K8, create a formula using the SUM function that calculates the total of range D17:D20 and subtracts it from the value in J8
Answer:
=(J8 - SUM(D17:D20))
Explanation:
Required
Add D17 to D20
Subtract the result from J8
Save the result in K8
To do this, we make use of a nested bracket.
The innermost bracket is to add up D17 To D20 using the sum function.
i.e. SUM(D17:D20)
While the outermost bracket will subtract the calculated sum from J8.
=(J8 - SUM(D17:D20))
The SUM function is used to Adds values, in which users can add different values, in cells or range references or a mix of each of them, and the further calculation can be defined as follows:
In this question, we use the "=(J8 - SUM(D17:D20))" function that's description can be defined as follows:
D17 to D20 AddSubtract the J8 resultSave K8 resultsWe use a nested bracket to do this.D17-D20 is added to the innermost bracket with the sum function.SUM, i.e. (D17:D20)The calculated amount from J8 is taken from the outermost bracket.Therefore the final answer is "=(J8 - SUM(D17:D20))".

Write a function, named FileLineCount(), that returns an integer and accepts a string. Pass the function the file name. It should then use a while loop to return the number of lines in a file. Hint: The function will be reading the file you just created above. g
Answer:
Explanation:
The following code is written in Python. It is a function that accepts a file string and uses that string to read the file in that location. Then it uses a while loop that keeps going until there are no more lines in the file. Each iteration it adds 1 to the count variables. Finally, it prints the count variable which contains the total number of lines in the file. The code has been tested and the output can be seen in the attached image below.
def countLines(file):
file = open(file, 'r')
count = 0
while file.readline():
count += 1
print(str(count) + " total lines")

Full question:
#Write a function called align_right. align_right should #take two parameters: a string (a_string) and an integer #(string_length), in that order. # #The function should return the same string with spaces #added to the left so that the text is "right aligned" in a #string. The number of spaces added should make the total #string length equal string_length. # #For example: align_right("CS1301", 10) would return the #string " CS1301". Four spaces are added to the left so #"CS1301" is right-aligned and the total string length is #10. # #HINT: Remember, len(a_string) will give you the number of #characters currently in a_string.
Answer and Explanation:
Comments have been used in the code to explain the program
Using Python
#first define the function with #parameters a_string and string_length
def align_right(ourString,stringLength):
#test to see if string is longer than the length passed
if len(ourString) > stringLength:
print(ourString)
#If not define variable aligned and use #rjust function to justify string to the #left leaving space left in stringLength
else:
aligned=ourString.rjust(stringLength)
#print the variable aligned

A school’s administration stores the following data for each student in an online system: name, class, and five electives. Select the data type that the school should use to store information on the electives.
Answer:
Array of Strings
Explanation:
I believe the best data type for this information would be an Array of Strings. This array would have a fixed size of 5 elements. One for each one of the five electives that the student will have. Then the individual electives will be String elements that are saved in the 5 indexes of the Array. This would allow all of the electives to be bundled into a single variable and accessed together or individually by the user. This would be the best and most efficient data type to store this information.

Kirsten manages the infrastructure that hosts her company's CRM platform. She currently has a production environment that all of the users access. However, she was recently reading about the concept of creating a second production environment where patches and updates are applied and then traffic is shifted over to the second environment once it has been tested. Which of the following describes the methodology that she is considering implementing?
a. Rolling deployment
b. Blue-green deployment
c. Duplicate deployment
d. Canary deployment
Answer:
The methodology that Kristen is considering to implement is:
d. Canary deployment.
Explanation:
This deployment type creates a second production environment (better called a testing environment). Here, patches and updates are first applied for testing purposes before shifting traffic to the main production environment. In a server environment, the idea of canary deployment is to first deploy the changes to a small subset of servers, test them before rolling out the changes to the rest of the servers. It enjoys some advantages over other deployment strategies because it allows for testing.

Write a python program that will find the longest word in a file. The program should print the word and the number of characters in that word. Hint you would be using dictionaries, string module, and files for this exercise.
Answer:
Explanation:
The following code is written in Python. It is a function that takes in the file location as a parameter and reads it. It then splits the text into a list and loops through the list. The length of every element is compared to the value in the variable length and if it is larger it saves that words length to the variable length and saves the word to the variable longestWord. These variables get printed at the end of the program. A test case has been provided and can be seen in the image below.
import re
def longestWordInFile(file):
file = open(file, 'r')
text = file.read()
wordList = text.lower()
wordList = re.split('\s', wordList)
length = 0
longestWord = ''
for word in wordList:
if len(word) > length:
length = len(word)
longestWord = word
print(longestWord + " is the longest with " + str(length) + " characters.")

GDP measures the production levels of
any nation. Which of the following
automatically improves if a nation's
production improves?
A. Standard of Living
B. Inflation
C. High unemployment
Answer:
A. Standard of Living
Explanation:
Gross Domestic Products (GDP) is a measure of the total market value of all finished goods and services made within a country during a specific period.
Simply stated, GDP is a measure of the total income of all individuals in an economy and the total expenses incurred on the economy's output of goods and services in a particular country. Also, Gross Domestic Products (GDP) is a measure of the production levels of any nation.
Basically, the four (4) major expenditure categories of GDP are consumption (C), investment (I), government purchases (G), and net exports (N).
Hence, the standard of living of the people living in a particular country automatically improves if a nation's level of productivity or production improves; they are able to easily pay for goods and services, as well as save and invest their money.
In contrast, inflation and high unemployment rate are indications of economic downturn, recession and low level of productivity (output) in a country; this would automatically affect the standard of living within such countries.

Data members and member functions jointly determine the characteristics and actions of the objects in a Class. Data members are the variables that make up the data, and member functions are the methods used to modify these variables.
What are the data member in a program?Members declared using any of the basic kinds as well as other types, such as pointer, reference, array types, bit fields, and user-defined types, are referred to as data members.
Any class may contain however many data members are necessary. The only situation in which a limitation might occur is when there is not enough memory.
Member data — information about the thing. Member functions — behavior-related aspects of the object-related functions A class is an object's blueprint. A class is a user-defined type that specifies the appearance of a certain type of object.
Therefore, radius, cylinder, print would be a data member.

What is the difference between ROM and RAM
Answer:
ROM : Read Only Memory.
RAM : Random Ascess Memory.
Answer:
RAM is the random access memory of your computer and ROM, which is a read-only memory.
RAM is a volatile storage memory that temporarily saves your files. ROM is non-volatile memory, which stores your computer instructions permanently.
Explanation:
RAM:-
RAM is a volatile memory that can store data while power is delivered.
It is possible to retrieve and modify data saved on RAM.
It is used to store data that must be processed temporarily by the CPU.
The CPU is able to access the saved data.
It's a memory of high speed.
ROM:-
ROM is a non-volatile memory that can retain information even when power is off.
ROM data can be read-only.
During computer bootstrap, it saves the necessary instructions.
The data stored on it cannot be accessed by the CPU without data being stored in RAM.
It's a lot lighter than RAM.
Write a program using a dictionary that reads in a single positive digit number [0 - 9] from the user at the keyboard. Your program will then be able to look up the digit key in the dictionary and print the digit value spelled out. If the user types in a number that is either more than one digit, negative, or a non int value, re-prompt the user for valid input. First, before demonstrating your test cases, print out a display copy of the key:value pairs in your dictionary in sorted order. Deliverable: yournameLab4.py Your source code solution and a copy of the run pasted into your source submission file. Be sure to comment out your run so that your .py file will still run in the grader test bed. Validate user input is a single positive digit [0 - 9].
