Does vigorous exercise affect concentration? In general, the time needed for people to complete a certain paper and pencil maze follows a Normal distribution, with a mean of 30 seconds and a standard deviation of three seconds. You wish to see if the mean time is changed by vigorous exercise, so you have a random sample of nine employees of your company (that you assume are representative of people in general) exercise vigorously for 30 minutes and then complete the maze. It takes them an average of = 31.2 seconds to complete the maze. Use this information to test the hypotheses

H0: = 30, Ha: 30

at the 1% significance level. The P value is 0.2302. From this, you determine that:

A.

Ha should be rejected.

B.

Ha should not be rejected.

C.

H0 should not be rejected.

D.

H0 should be rejected.
