Project #10909 - Statistics3

We’re trying to test whether a new, low-fat diet actually helps obese people lose weight. 100 randomly assigned obese people are assigned to group 1 and put on the low fat diet. Another 100 randomly assigned obese 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 4 months, the mean weight loss was 8 lbs for group 1 (s=5) and 7 lbs (s=4) for group 2 (control group). Test the hypothesis that the low fat diet does not help obese people lose weight. (alpha =5%)
