The water diet requires you to drink two cups of water every half hour from the time you get up until you go to bed, but otherwise allows you to eat whatever you like. Four adult volunteers agree to test the diet. They are weighed prior to beginning the diet and after six weeks on the diet. Their weights (in pounds) are:
Subject A B C D
Weight before diet 180 125 240 150
Weight after diet 170 130 215 152
We want to estimate the mean difference (before ā after) in weight. What is the appropriate 95% confidence interval?
