Past experience indicates that the time for high school seniors to complete a standardized test is a normal random variable with a mean of 35 minutes. If a random sample of 20 high school se-niors took an average of 33.1 minutes to complete this test with a standard deviation of 4.3 minutes, test the hypothesis at the 0.025 level of significance that \mu=35 minutes against the alternative that \mu<35 minutes.
Let t0.025.19 = 2.09.
