The data were collected in a clinical trial of the use of estrogen patches in the treatment of postnatal depression. Using posttreatment depression score as the response, formulate a suitable model for examining the effects of the baseline measurements and treatment group on the response. Construct a suitable 95% confidence interval for the treatment effect and state your conclusions based on the analyses you have carried out.
