A state meat inspector has been given the assignment of estimating the mean net weight of packages of ground turkey labeled "3 pounds." Of course, she realizes that the weights cannot be precisely 3 pounds. She takes a sample of 36 packages, and found that the mean weight is 3.01 pounds, with a standard deviation of .03 pounds. Determine a 95% confidence interval for the population mean.
