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 seconds. You wish to see if the mean time is changed by vigorous exercise, so you have a group of nine college students exercise vigorously for 30 minutes and then complete the maze. Assume that remains unchanged at 3 seconds. You decide to test the hypotheses H ₀: = 30 versus H _a: 30 at the 1% significance level. What is the range of -values for which you will not reject H ₀?
