Assignment:
Using a Dummy Variable Use the data in Table and, for a predictor variable, use the dummy variable of sex (coded as 0 = female, 1 = male). (The data in Table are based on data from the National Health and Nutrition Examination.) Given that a mother is 63 in. tall and a father is 69 in. tall, find the multiple regression equation and use it to predict the height of (a) a daughter and (b) a son.
