Question: The manager of a local fitness center wants an estimate
The manager of a local fitness center wants an estimate of the number of times members use the weight room per month.

Assuming that the monthly number of visits is normally distributed, determine a 95% confidence interval for the average monthly usage of all members of this fitness center.
