Do male and female servers work the same number of hours? A sample of 29 female servers worked an average of 23 hours per week, with a standard deviation of 4. A sample of 16 male servers worked an average of 24 hours per week, with a standard deviation of 2. Construct a 95% confidence interval for the mean difference in hours worked for male and female servers. You may assume that the populations are normal. Lower bound on CI = (use two decimal places) Upper bound on CI = (use two decimal places)
