Answer: 972π in³
Step-by-step explanation:
We will use the proper formula to solve for the volume of the sphere.
-> The radius (r) is half the diameter. 18 in / 2 = 9 in
V = πr³
V = π(9)³
V = * (9)³ * π
V = 972π in³
The volume is 972π in³
Answer:
The sample size required is 225.
Step-by-step explanation:
The confidence interval for population mean (<em>μ</em>) is:
The margin of error is:
Given:
The margin of error is, <em>MOE</em> = 0.04
The confidence level is 95.44%.
The critical value of <em>z</em> for 95.44% confidence interval is:
So, .
Determine the sample size as follows:
Thus, the sample size required is 225.
