Scenario: Return to the NHANES2016 data table. Exclude and hide respondents under age 18, leaving both female and male adults.

a. Perform a regression analysis for adult respondents with BMI as Y and use waist circumference and gender as the independent variables. The relevant columns are BMXBMI, BMXWAIST, and RIAGENDR. Discuss the ways in which this model is or is not an improvement over a model that uses only waist circumference as a predictor.

b. Perform a regression analysis extending the previous model, and this time, add an interaction term between waistline and gender. Report and interpret your findings.
