Do male and female servers work the same number of hours? A sample of 23 female servers worked an average of 27 hours per week, with a standard deviation of 3. A sample of 17 male servers worked an average of 22 hours per week, with a standard deviation of 5. 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. We are 80% confident that the interval f1 - μ2 in hours worked between male and female servers. contains the true mean difference Which of the following do you conclude? O Female and male servers work about the same number of hours on average. Female servers work more hours on average. O Male servers work more hours on average.
