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 seconds. You wish to see whether the mean time μ 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 o remains unchanged at 3 seconds. The hypotheses you decide to test are Ho: μ = 30 versus H₁ : µ ‡ 30. Suppose it takes the nine students an average of x = 32.05 seconds to complete the maze. At the 1% significance level, what can you conclude? Ho should be rejected because the P-value is less than 0.01. Ho should not be rejected because the P-value is greater than 0.01. O Ha should be rejected because the P-value is less than 0.01. Ha should not be rejected because the P-value is greater than 0.01.
