Assess how B.M.I. varies by gender. Use the tab “B.M.I. of Boys and Girls”. These are the same study subjects described in the “All Variables” tab, but the data on gender and B.M.I. is set up in a way that will facilitate running the statistical analysis to assess whether there is a difference between the B.M.I. of boys and girls. What test will you use? What does the test reveal?
