Sleep Time A person read that the average number of hours an adult sleeps on Friday night to Saturday morning was 7.2 hours. The researcher feels that college students do not sleep 7.2 hours on average. The researcher randomly selected 15 students and found that on average they slept 8.3 hours. The standard deviation of the sample is 12 hours. At a=0.05, is there enough evidence to say that college students do not sleep 7.2 hours on average? Assume that the population is approximately normally distributed. Use the critical value method and tables. Part 1 of 5 (a) State the hypotheses and identify the claim. Hou = 7.2 not claim Hu 7 7.2 claim This hypothesis test is a two-tailed v test, Part: 1/5 Part 2 of 5 (b) Find the critical value(s). Round the answer(s) to three decimal places. If there is more than one critical value, separate them with commas. Critical value(s):
