3. The average time a teenager watches tv in a day is 93 minutes. Suppose that the population is normally distributed with a o = 12 and a test of hypothesis Ho: = 93 versus Ha>93 will be performed with a sample of size 9. Construct the rejection region for the test for the choice a = .05 4. The average GPA of a high school is 2.86. Suppose that the population is normally distributed with ag = .7 and a test of hypothesis Ho: = 2.86 versus Ha 2.86 will be performed with a sample of size 8. Construct the rejection region for the test for the choice a = .01 5. The average number of skittles in a bag is 42. Suppose that the population is normally distributed with a o = 5 and a test of hypothesis Ho: = 42 versus Ha: μ< 42 will be performed with a sample of size 7. Construct the rejection region for the test for the choice α = .1
