A new diet is developed to help people lose weight. 50 people tried the diet and had an average weight loss of 8 pounds over 30 days with a standard deviation of 2 pounds. A control group of 100 people tried a standard diet of fruits and vegetables also had an average weight loss of 9 pounds with a standard deviation of 1.2 pounds. Using a 5% significance determine if the new diet is better than eating fruits and vegetables. Take as population 1 the group on the new diet. Give the hypotheses. Null: There is no difference in the average weight loss between the two diets. Alternative: The average weight loss on the new diet is more than the average weight loss on the fruit and vegetable diet. Null: There is no difference in the average weight loss between the two diets. Alternative: The average weight loss on the new diet is less than the average weight loss on the fruit and vegetable diet. Null: There is no difference in the average weight loss between the two diets. Alternative: The average weight loss on the new diet is not equal to the average weight loss on the fruit and vegetable diet. O No answer text provided.
