Can you conclude that the population standard deviation of TV watching times for teenagers is greater than 2.89? Use the a = 0.01 level of significance. Part 1 of 5 State the appropriate null and alternate hypotheses. Ho: 0 = 2.89 H 1:0 > 2.89 This hypothesis test is a right-tailed v test . Part 2 of 5 Find the critical value. Round the answer to three decimal places, For a= 0.01, the critical value is 67.459 Part: 2 / 5 Part 3 of 5 Compute the test statistic, Round the answer to three decimal places. X
