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
Median: 35
Range: 20
Variance: 59.5
S.D.: 7.72
(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.

  • Statistics - ,

    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.
