Past experience indicates that the time required for high school seniors to complete a
standardized test is a normal random variable with a standard deviation of 7 minutes.
Test the hypothesis that o = 7 against the alternative that o<7 if a random sample of the
test times of 18 high school seniors has a standard deviation s = 5.83. Use a 0.10 level
of significance.
