![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.

Alternative: The average weight loss on the new diet is not equal to the average
weight loss on the fruit and vegetable diet.
