Question
The water diet requires you to drink 2 cups of water every half hour from when you get up until you go to bed but eat anything you want. Four adult volunteers agreed to test this diet. They are weighed prior to beginning the diet and 6 weeks after.
Their weights in pounds are
Person 1 2 3 4
Weight Before 180 125 240 150
Weight After 170 130 215 152
What can we conclude by these results about the water diet? Conduct a paired t-test and state your result at the significance level = .05.
