Question

i need this, the t statistic, and p value

A study compared different psychological therapies for teenage girls suffering from anorexia. The study employed randomization in assigning girls to one of three therapies, only one of which is considered in this example. Each girl's weight was measured before and after a period of therapy. The variable of interest was the weight change, defined as weight at the end of the study minus weight at the beginning of the study. The weight change was positive if the girl gained weight and negative if she lost weight. For each of 17 girls who received the family therapy, the changes in weight were the following. Complete parts a through c below. 11 11 7 9 14 -2 -1 5 24 -4 -3 12 12 9 2 7 a. Plot these data with a dot plot and summarize. Choose the correct dot plot below. O A. . -15 Weight Change X = Pounds b.
