Six subjects took part in a weight loss study. Each subject was weighed at the beginning of the study. The subjects then completed a six-week diet and exercise plan. They were weighed after completing the plan.

Subject	Weight Before (lbs.)	Weight After (lbs.)
1	285	253
2	265	230
3	302	285
4	293	298
5	269	255
6	288	271

The results are shown below The variable Weight Change is defined as the Weight After minus the Weight Before. What is the average weight change? Include 1 decimal place in your answer.

In a test of the Weight Watchers weight loss program, weights of 42 subjects are recorded before and after the program such that the x-value is an individual's weight at the start of the program and the y-value is the same person's weight after one year on the program. The mean of the starting weights was 192.7 pounds. The mean of the weights after one year was 178.2 pounds. The regression equation was found to be yˆ=.802x+30.27ŷ=.802x+30.27.

Female undergraduates in randomized groups of 10 took part in a self-esteem study. The study measured an index of self-esteem from the point of view of competence, social acceptance, and physical attractiveness. Let x1, x2, and x3 be random variables representing the measure of self-esteem through x1(competence), x2 (social acceptance), and x3 (attractiveness). Higher index values mean a more positive influence on self-esteem. Variable Sample Size Mean x Standard Deviation s Population Mean x1 10 20.25 3.27 μ1 x2 10...
