Example 6.4 (page 148) described a study about therapies for teenage girls suffering from anorexia. For the 17 girls who received the family therapy, the changes in weight were 11, 11, 6, 9, 14, −3, 0, 7, 22, −5, −4, 13, 13, 9, 4, 6, 11.

Some Stata output (edited) for the data shows

-------------------------------------------------

Variable | Obs Mean Std. Err. Std. Dev.

change | 17 7.294118 ?? 7.183007 mean = mean(change) t = ??

Ho: mean = 0 degrees of freedom = ??

Ha: mean != 0 Ha: mean > 0 Pr(|T| > |t|) = 0.0007 Pr(T > t) = ??
