Answer:
Standard error = 0.34
t-statistic = 11.18
Step-by-step explanation:
Given Data:
Mean difference d = 3.8
Standard deviation S.D = 1.36
Number of people = 16
The appropriate test are:
1. Standard error
2. T- statistic
1. Calculating the standard error using the formula;
Standard error = S.D/√n
= 1.36/√16
= 1.36/4
= 0.34
2. Calculating the t-statistic using the formula;
t-statistic = d/(S.D/√n)
= 3.8/(1.36/√16)
= 3.8/(1.36/4)
= 3.8/0.34
= 11.18

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.
