Hil!Alternative hupothsis)):H<2 2. The average amount of calories in a box of cookies is 120 calories. A person thinks this number should be different. State the null and alternative hypothesis. 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 H,: u = 93 versus H,: µ > 93 will be performed with a sample of size 9. Construct the rejection region for the test for the choice a = .05 The average GPA of a high school is 2.86. Suppose that the population is normally distributed with ao = .7 and a test of hypothesis H,: µ = 2.86 versus H, : u # 2.86 will be performed with a sample of size 8. Construct the rejection region for the test for the choice a = .01 ne average number of skittles in a bag is 42. Suppose that the population is normally distributed th a o = 5 and a test of hypothesis H,: µu = 42 versus Ha: µ < 42 will be performed with a mple of size 7.
