It's a 2 part question.

36 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/ Student BMI (kg/ Intervention m2 Control m2) Group Group 18.6 21.6 18.2 18.9 C 19.5 19.4 18.9 22.6 24.1 23.6 ) Assuming that all the necessary conditions are met (normality, independence, etc.) carry out the appropriate statistical test o determine if the new exercise program is effective. Use an alpha level of 0.05. Do not assume equal variances. Construct a 95% confidence interval about your estimate for the average difference in BMI between the groups. A) Ho: 1=2 Ha: 1
