What kind of health information is not collected in the National Health Survey?

A Canadian study measuring depression level in teens (as reported in the Journal of Adolescence, vol. 25, 2002) randomly sampled 112 male teens and 101 female teens, and scored them on a common depression scale (higher score representing more depression). The researchers suspected that the mean depression score for male teens is higher than for female teens, and wanted to check whether data would support this hypothesis.The following hypotheses were tested:H0: μ1 = μ2Ha: μ1 > μ2The following is the (edited) output for the test:Which of the following is an appropriate conclusion based on the output? The data do not provide sufficient evidence to conclude that the mean depression score of male teens is larger than that of female teens. The data provide sufficient evidence to conclude that male and female teens do not differ in mean depression score. The data do not provide sufficient evidence to reject H0, so we accept it, and conclude that male and female teens do not differ in mean depression score. The data provide sufficient evidence to reject H0 and to conclude that the mean depression score for male teens is larger than that of female teens.
