QUESTONS AND ANSWERS

Mary has a dataset with height (in inches), weight (in lbs), and math_score (final exam score out of 100) of 300 students in an undergraduate math course. She creates another field called BMI (Body Mass Index) calculated as BMI=703*(weight/height2). She wants to examine if math_scoreis related to height, weight and BMI. She plans to use a linear regression model math_score ~ height+weight+BMI to study this relationship. Leonard hears about Mary’s plan and tells Mary that BMI should not be...
