A study was conducted in which students were asked to estimate the number of calories in a cheeseburger. One group was asked to do this after thinking about a calorie-laden cheesecake. A second group was asked to do this after thinking about an organic fruit salad. The mean number of calories estimated was 771 for the group that thought about the cheesecake and 915 for the group that thought about the organic fruit salad. Suppose that the study was based on a sample of 20 students in each group, and the standard deviation of the number of calories estimated was 128 for the people who thought about the cheesecake first and 147 for the people who thought about the organic fruit salad first. Complete parts (a) through (e). a. State the null and alternative hypotheses if you want to determine whether the mean estimated number of calories in the cheeseburger is lower for the people who thought about the cheesecake first than for the people who thought about the organic fruit salad first. Let u, represent the mean number of calories estimated by the people who thought about the cheesecake first and u2 represent the mean number of calories estimated by the people who thought about the organic fruit salad first. Choose the correct answer below. OA. HO: MISH2 OB. HO: H1 = H2 Hy : H 1 > H 2 Hy: Hy # H2 OC. HO: H1 # H2 OD. HO: H1 2 H2 Hy: H1 = H2 Hy : My
