Diet and Blood Sugar. A doctor wants to evaluate a new diet for diabetic patients. He measures the blood sugar levels (measured 2-3 hours after a meal) of 7 patients before and one month after using the new diet. Test the claim that the diet changes the average blood sugar level. Patient Before Diet After Diet A B C D E F G 210 180 230 230 180 210 210 190 210 180 200 170 230 180 (a) Why are these paired data? All of the after diet blood sugar values are lower than the before diet blood sugar values. O Patient are paired up. This table does not have paired data; there is no clear relationship between the top and bottom values in any column. O Some patients are on diet and some are not on diet. Most of the after diet blood sugar values are lower than the before diet blood sugar values. O The before and after values in each column are from the same patient. (b) Write the hypotheses in symbols. O Ho Hdiff-before-after = 0 Ha: Hdiff-before-after < 0 O Ho Hdiff-before-after = 0 Ha Hdiff-before-after* 0 O Ho Hdiff-before-after = 0 Ha: Hdiff-before-after > 0 (c) Put the list of differences in your calculator and use T-Test to find the p-value. (please round to four decimal places) P = (d) What is the conclusion of the hypothesis test? O Since p
