We are trying to test whether, a new low fat diet actually helps obese people lose weight. 150 randomly obese people are assigned to group 1 and put on a low-fat diet. Another 150 people are assigned to group 2 and put on a diet of approximately the same amount of food, but not as low in fat. After 6 months, the mean weight loss was 24pounds for group 1 with a standard deviation of 7 pounds, and for group 2 the mean weight loss was 20 pounds with a standard deviation of 5 pounds. Is the low fat diet more effective? Perform a hypothesis test at the 1% significance level. a) Construct an appropriate confidence interval for Problem and state the conclusion
