Question: You take a sample of 22 from a population of test scores, and the mean of your sample is 60.
- You know the standard deviation of the population is 10. What is the 99% confidence interval on the population mean?
- Now assume that you do not know the population standard deviation, but the standard deviation in your sample is 10. What is the 99% confidence interval on the mean now?
