I need help with (b): A small company with 5 employees wants to know some statistics about their employee's ages. They surveyed the 5 employees and found that their ages were: 22, 29, 35, 37 and 42.
Mean age: 33
(b) How would your answers change if this was a sample of 5 employees from a company of 10,000? I believe it would not change the answers.
Your SD is the sample SD. Your population SD is 6.90.
How does it change if population larger, and sample size stay at 5? Does not change.
