Considering that we have the standard deviation for the sample, the t-distribution should be used to solve this question.
<h3>When should the z-distribution and the t-distribution be used?</h3>
- If we have the standard deviation for the sample, the t-distribution should be used.
- If we have the standard deviation for the population, the z-distribution should be used.
In this problem, there is a sample standard deviation of 0.5 hours, hence the t-distribution should be used.

Answer:
16u^2 and 16u
Step-by-step explanation:
Hello! :)
Well, the only difference in the two points is from the 0 and the -4. That means the square is 4 units in length and width.
A=B*H=4*4=16 u^2
P=B*4=4*4=16 u
Answer:
9 17/20
Step-by-step explanation:
4 1/4+5 3/5
4 5/20+5 12/20
4+5=9
5/20+12/20=17/10
9 17/20
