Among the most exciting aspects of a university professor's life are the departmental meetings where such critical issues as the color the walls will be painted and who gets a new desk are decided. A sample of 20 professors was asked how many hours per year are devoted to such meetings. The responses are listed below. Assuming that the variable is normally distributed with a standard deviation of 7 hours, estimate the mean number of hours spent at departmental meetings by all professors. Use a confidence level of 96%. 8, 10, 16, 2, 19, 4, 18, 13, 16, 15, 10, 8, 5, 11, 18, 2, 12, 21, 8, 16 Note: For each confidence interval, enter your answer in the form (LCL, UCL). You must include the parentheses and the comma between the confidence limits. You should use technology to help you with this problem (Minitab :) ). Give your answers to at least 2 decimal places. Confidence Interval=
