You can put this solution on YOUR website! Forty-nine items are randomly selected from a population of 500 items. The sample mean is 40 and the sample standard deviation 9.
-------------------
Develop a 99% confidence interval for the population mean.
Sample mean = 40
ME = 2.5758[9/sqrt(49)] = 3.312
-----
The confidence interval is between 40-3.312 and 40+3.312
