Suppose a researcher is interested in the effectiveness in a new childhood exercise program implemented in a SRS of schools across a particular county. In order to test the hypothesis that the new program decreases BMI (Kg/m2), the researcher takes a SRS of children from schools where the program is employed and a SRS from schools that do not employ the program and compares the results. Assume the following table represents the SRSs of students and their BMIs.

Student BMI (kg/m2) Student BMI (kg/m2)

Intervention Group Control Group

A 18.6 A 21.6

B 18.2 B 18.9

C 19.5 C 19.4

D 18.9 D 22.6

E 24.1

F 23.6

A) Assuming that all the necessary conditions are met (normality, independence, etc.) carry out the appropriate statistical test to determine if the new exercise program is effective. Use an alpha level of 0.05. Do not assume equal variances.

B) Construct a 95% confidence interval about your estimate for the average difference in BMI between the groups.
