Use MegaSTAT to validate the result

Assignment: Determine confidence estimate, Z values, and p-value Instructions 1. Among the most exciting aspects of the life of a manager are the departmental meetings where critical issues such as the color of the walls and who gets a new desk. A sample of 20 was asked managers how many hours a year are spent in these meetings. Assuming that the variable is normally distributed with a standard deviation of 8 hours. Determine the confidence estimate of the average number of hours spent to the departmental meeting of all managers. Use a confidence level of 95%. Data: 14, 17, 3, 6, 17, 3, 8, 4, 20, 15, 7, 9, 0, 5, 11, 15, 18, 13, 8, 4. 2. Determine the critical Z value, Z statistic, show the rejection region. Determine the p-value, interpret the result, and sketch the distribution of the curve. When = 6, n = 25, x = 21.63, a = .05, = 22, when the statement of the hypotheses are as follows: Alternative hypothesis: H1:
