Answer:
By using hypothesis test at α = 0.01, we cannot conclude that the proportion of high school teachers who were single greater than the proportion of elementary teachers who were single
Step-by-step explanation:
let p1 be the proportion of elementary teachers who were single
let p2 be the proportion of high school teachers who were single
Then, the null and alternative hypotheses are:
: p2=p1
: p2>p1
We need to calculate the test statistic of the sample proportion for elementary teachers who were single.
It can be calculated as follows:
where
- p(s) is the sample proportion of high school teachers who were single (
) - p is the proportion of elementary teachers who were single (
)
- N is the sample size (180)
Using the numbers, we get
≈ 1.88
Using z-table, corresponding P-Value is ≈0.03
Since 0.03>0.01 we fail to reject the null hypothesis. (The result is not significant at α = 0.01)
Answer:
<h2>a. 2,025 ft</h2><h2>b. 8,100 is a perfect square. </h2>
Step-by-step & explanation:
<em>It is a perfect square because if it wasn't, it wouldn't be equally a whole number when divided by 4 or 2,025 exactly on ALL 4 sides and when finding the root of 8,100 it's a perfect 90. As you should already know a perfect square has a given 90 degree angle.</em>
Tarp = 8,100 sq ft.
- anchored corners at the base.
- Square infield.
Well if there's 4 bases, divide 8,100 by 4.
8,100 / 4 = 2,025
One base to another base is 2,025 ft.
Answer:
3 x 4 = 12
4 x 5 = 20
5 x 2 = 10
Step-by-step explanation:
3 + 3 + 3 + 3 = 12
3 four times equals 12
This is the same for the others
4 + 4 + 4 + 4 + 4 = 20
Four 5 times equals 20
