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

O A. Most of the data fall between 2 and 14. There appears to be an outlier on the right. The distribution doesn't appear normal.
B.
Most of the data fall between 4 and 5. There appears to be an outlier on the right. The sample size is small, but there is no evidence of severe non-normality.
C. Most of the data fall between 2 and 14. There are no outliers. The sample size is small, but there is no evidence of severe non-normality.
D. Most of the data fall between 12 and 25. There are no outliers. The sample size is small, but there is no evidence of severe non-normality.
