A new runner has decided to purchase a new pair of running shoes. He has narrowed his choices to two brands, each of which would be appropriate for his use. His concern is whether there is a significant difference in the average wear between the two brands of shoes. He enlisted a random sample of 6 veteran runners to test the shoes. Each runner wore each brand of shoe until it wore out. What method of analysis is more appropriate to use for this problem
Answer:
Paired difference t test
Step-by-step explanation:
The paired difference t test is a type of statistical test which is used to examine if difference exists in th population mean of two samples. The paired difference test usually involves samples taken within subjects. That is, the sample mean for each set of measurement is taken from the Same subject, In the scenario described above, the subjects which are the 6 veteran runners each wore each of the two shoe brands, this means that two readings were produced by each runner ; one reading for brand A and the other brand B.
The difference between the two readings are taken for each runner and used to perform a hypothesis test:
t = μd/ (s/√n)
s = sample standard deviation ; n = sample size ; μd = mean difference
A school store has 1200 pencils in stock, and sells an average of 25 pencils per day. The manager reorders when the number of pencils in stock is 500. In how many days will the manger have to reorder? The equation that the manger uses to calculate number of days is 1200 - 25x =500.
A 35 DAYS
b 45 DAYS
C 28 DAYS
D 17 DAYS
Answer:
C. 28 DAYS
Step-by-step explanation:
You take the total ammount of pencils and subtract the minimum stock (y intercept)
1200-500 = 700
700 divided by the slope of the equation (how many pencils a day is sold) 25
700/25 = 28

Answer:
The answer is b
Step-by-step explanation:
In the given figure p ∥ q , and t is a transversal then find the measures of a, b, c, d and e.
Answer:
d=125-degree since p and q are parallel
b=d=125-degree since b and d are vertically opposite angles
a+d= 180-degree since they lie in straight line
Hence, a=180-125=55-degree
c=a=55-degree since a and c are vertically opposite angle
f=a=55-degree since a and f are alternate angle
e=f=55-degree since e and f are vertically opposite angle

If d(4)=68. Thus, joe travels 68 mi in 4 hours. How many mi does Joe travel in 45 min
Answer:
12.75 miles
Step-by-step explanation:
Changing hours to minutes
4 hours 4*60 = 240 minutes
Now we can use a ratio to solve
68 miles x miles
------------- = -----------------
240 minutes 45 minutes
Using cross products
68*45 = 240x
Divide each side by 240
68*45 /240 = x
12.75 miles
Answer:
12.75 MILES
Step-by-step explanation:
if he travels 68 miles in 4 we should find how many miles per hour
to find this we divide 68/4 which is 17
So if he is going 17 MPH then to find how far he travels in 45 min we should multiply by 3/4
17 x 3/4 is 12.75
12.75 MILES
On each coordinate plane, the parent function f(x) = |x| is represented by a dashed line and a translation is represented by a solid line. Which graph represents the translation g(x) = |x + 2| as a solid line?
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (2, 0).
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (0, negative 2).
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (negative 2, 0).
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (0, 2).
Using shifting concepts, we get that the graph that represents the translation g(x) = |x + 2| as a solid line is:
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (-2, 0).
--------------------------------------------------
Shifting a function f(x) a units to the left is the same as finding f(x + a).--------------------------------------------------
The vertex of the function f(x) = |x| is at the point where x = 0, and thus, f(x) = 0. Thus, the vertex of the dashed line is at (0,0).The vertex of the function g(x) = |x + 2| is at the point where [tex]x + 2 = 0 \rightarrow x = -2[/tex], g(-2) = |-2 + 2| = 0. Thus, the vertex of the solid line is at (-2,0).Thus, the correct option is:
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (-2, 0).
At the end of the exercises, there are are the graphs of those two functions, considering the dashed line as the red line and the solid line as the blue line.

If f(x) = -2[x] + 8, what is f(-1.8)?
4
6
10
12
Answer:
it's 12!
Step-by-step explanation:
Answer:
C. 10
Step-by-step explanation:
First, you plug in f(-1.8) into the original equation.
f(-1.8) = -2 (-1) + 8
The reason why I rounded -1.8 to -1 is because we're using the ceiling function, which means we need to round up (the brackets tell you in Edge but not on Brainly). Rounding up a negative number means we are going closer to 0. The next whole number close to -1.8 on the right will be -1.
Now solve:
f(-1.8) = 2 + 8 = 10
The answer is 10 if f(-1.8)

If the mean number of years between asbestos exposure and death is found to be 25 years with a standard deviation of 7 years in a particular county, what is the probability that the mean number of years between asbestos exposure and death will be between 22 and 29 years in a sample of 50 people taken from that community
Answer:
0.9988 = 99.88% probability that the mean number of years between asbestos exposure and death will be between 22 and 29 years.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
The mean number of years between asbestos exposure and death is found to be 25 years with a standard deviation of 7 years in a particular county
This means that [tex]\mu = 25, \sigma = 7[/tex]
Sample of 50:
This means that [tex]n = 50, s = \frac{7}{\sqrt{50}}[/tex]
What is the probability that the mean number of years between asbestos exposure and death will be between 22 and 29 years?
This is the p-value of Z when X = 29 subtracted by the p-value of Z when X = 22.
X = 29
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{29 - 25}{\frac{7}{\sqrt{50}}}[/tex]
[tex]Z = 4.04[/tex]
[tex]Z = 4.04[/tex] has a p-value of 1.
X = 22
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{22 - 25}{\frac{7}{\sqrt{50}}}[/tex]
[tex]Z = -3.03[/tex]
[tex]Z = -3.03[/tex] has a p-value of 0.0012.
1 - 0.0012 = 0.9988
0.9988 = 99.88% probability that the mean number of years between asbestos exposure and death will be between 22 and 29 years.
