(1 point) Remaining time: 196:36 (min:sec) The time needed for college students to complete a certain paper-and-pencil maze follows a normal distribution with a mean of 30 seconds and a standard deviation of 3.5 seconds. You wish to see if the mean time / is changed by vigorous exercise, so you have a group of 20 college students exercise vigorously for 30 minutes and then complete the maze. It takes them an average of I = 29.5 seconds to complete the maze. Use this information to test the hypotheses Ho : H = 30 Ha : u # 30 Conduct a test using a significance level of a = 0.05. (a) The test statistic (b) The positive critical value, z* = (c) The final conclusion is A. We can reject the null hypothesis that u = 30 and accept that u # 30. O B. There is not sufficient evidence to reject the null hypothesis that / = 30. Note: You can earn partial credit on this problem. Doc preview answers Problem 14.
