The meaning of significance. Asked to explain the meaning of "statistically significant at the α=0.05 level," a student says: "This means that the probability that the null hypothesis is true is less than 0.05." Is this explanation correct? Why or why not?
Answer:
This explanation is not correct
Explanation:
Significance level is the probability that the null hypothesis rejected is in fact true. If we say there is a significance level of 0.10 or 10%(α=0.10 level) then there is a 10% chance of incorrectly rejecting the null hypothesis when there is actually no difference.
If we wish to reach a conclusion on rejection or acceptance of the null hypothesis, we could use the p value(the probability that observed results or more extremee results are true given null hypothesis)which we compare with the significance level to conclude. If the significance level is 0.10 and p value is 0.07(since p value is less than significance level) , we reject the null hypothesis and vice versa.
The significant level, α = 0.05 level specifies a probability of the correctness of the null hypothesis.
The student is correct in the statement "This means that the probability that the null hypothesis is true is less than 0.05"
Reasons:
The significant level specifies the the likelihood of rejecting a true null
hypothesis, such that a 5% significance level indicates that the risk of
drawing a conclusion that there is a difference in a sample, when the
samples are similar is 5%, and therefore, the probability that null
hypothesis is true is 5% or 0.05.
The level of significance is a specification that indicates the amount of
evidence required within a sample to allow the rejection of the null
hypothesis, and reach a conclusion that the observed effect is statistical
significant at the α = 0.05 level.
Therefore;
The statement by the student that "This means that the probability that the null hypothesis is true is less than 0.05" is correct.

There are 3 times as many dogs as cats.
If the total number of dogs and cats is 16, how many dogs are there?
Answer:
there are 12 dogs.
Step-by-step explanation:
d= dogs now plug in the 4 into your equation.
c= cats d=3(4)
d+c=16 d=12
3c+c=16
4c=16 SO THEREFORE THERE ARE 12 DOGS :)

I need help for math plz :(
Answer:
Option D
Step-by-step explanation:
Set of data in terms of ordered pairs represents a function when output value of each input value is different.
Option A
Since, for every value of x there is a different value of y, it's a function.
Option B
In each ordered pair, for every value of x there is a different value of y.
Therefore, it's a function.
Option C
From the given graph, for every value of x there is a different value of y.
Therefore, it's a function.
Option D
From the given set of ordered pairs we find for x = 1 there are two values of y (y = 4 and 3).
Therefore, the given set of ordered pairs doesn't represent a function.
Option D is the answer.
write 5/6 - 7/9 in simplest form
9514 1404 393
Answer:
1/18
Step-by-step explanation:
18 is a suitable denominator for both fractions:
5/6 = 15/18
7/9 = 14/18
Then the difference is ...
5/6 -7/9 = 15/18 -14/18 = (15 -14)/18 = 1/18

The balance of a bank account is given for two consecutive weeks:
Week 1: -$8
Week 2: -$10
During which week does the account have more money in it ? How do you know?
Which balance has the greater absolute value? How do you know ?
Answer:
Step-by-step explanation:
there are more money during the week 1 because having a -$8 balance is better than having a -$10 balance, -8 > -10
week 2 has a greater absolute value
| -10| = 10 and |-8| =8 and becasue 10> 8 then |-10| > |-8|
which equation below has a slope of 1/4?
Answer:
The answer is 1, 2, and 3 only
Step-by-step explanation:
Math
Way
The equations which have slope 1/4:
ii. (y - 3.5) = 0.25(x - 2.75)
iii. 5x - 20y = 32
What is the equation of line?The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.
The slope-intercept form of a linear equation is y = mx + b, where m is the slope.
I. y = x - 5 is in slope-intercept form, so we can see that its slope is 1.
II. (y - 3.5) = 0.25(x - 2.75) can be rewritten in slope-intercept form as y = 0.25x + 2.1875. Therefore, its slope is 0.25 or 1/4.
III. 5x - 20y = 32 can be rewritten in slope-intercept form as y = (1/4)x - (4/5). Therefore, its slope is 1/4.
IV. 5x + 20y = 32 can be rewritten in slope-intercept form as y = (-1/4)x + (4/5). Therefore, its slope is -1/4.
So, only equations II, and III have a slope of 1/4.

As of the moment I am writing this question, the population of the United States is 326,891,705 people. You are building an app that targets the US population and expect to get 1/10 of 1% of the population using your app in the first 4 months. The estimated data you need to store per user averages 10 GB. What is the minimum storage you must plan to have in place for app to serve the users in the first 4 months
Answer:
3.3 PB
Step-by-step explanation:
It is given tat the population of the U.S = 326,891,705 people.
Population expected to use the app in first 4 months = 1/10 of 1%
Storage capacity of an user is = 10 GB
Therefore,
[tex]$\frac{1}{10} \text{ of}\ 1$[/tex] % = 0.1%
= 0.001
The user content = 0.001 x 326,891,705
= 326891.705 users
10 GB storage per user.
Therefore,
Size = 326891.705 x 10
= 3268917.05 GB
= 3.26 PB
Hence size of the minimum storage would be 3.3 PB.

Explanation:
It's the third option because if you put a piece of paper in the corner its a lil more than 90 degrees, so it wouldn't be B (there's a little more white space left). And it obviously wouldn't be A because that's self explanatory, lol.
And you can't make a perfect square in the inside of the angle so that's another way to tell.
