Do male and female servers work the same number of hours? A sample of 24 female servers worked an average of 40 hours per week, with a standard deviation of 4. A sample of 22 male servers worked an average of 28 hours per week, with a standard deviation of 3. Construct a 80% confidence interval for the mean difference in hours worked for male and female servers. Assume that the populations are normal with unequal variances. Round your answers to three decimal places, and use four decimal places for any interim calculations. Hint: Identify the type of t-procedure, and complete the confidence interval accordingly. We are 80% confident that the interval μ1 - ₂ in hours worked between male and female servers. contains the true mean difference
