STATA:

Use the Weight dataset link: https://drive.google.com/open?id=1BpxXaiYD-CPpVTo6ifMOAI5H8W7vH2mP

First create three body mass index (BMI) groups: 30 . ( BMI=weight(kg)(height(m))2 )Note that you will have to convert the data to the correct units.

Test the hypothesis that there is an overall mean difference in systolic blood pressure (sbp) levels among the three different BMI groups.

Write down the null and alternative hypotheses

Check the assumptions of your test. Try with and without transformations on the data.

Conduct the test (i) with and (ii) without transformations on the data.

Perform pairwise comparisons of the means using a multiple comparison adjustment (i) with and (ii) without transformations on the data.

Interpret your results with and without transformations of the data and decide which is most appropriate.
