The following multiple regression printout can be used to predict a person's height (in inches) given his or her shoe size and gender, where gender = 1 for males and O for females. Regression Analysis: Height Versus Shoe Size, Gender Coefficients Term Coef SE Coef T-Value 55.27 1.161 P-Value 0.000 0.000 Constant 1.03 53.66 Shoe Size 0.11 Gender 2.579 0.486 5.31 0.000 (a) Find the value of the test statistic for shoe size. (Round your answer to two decimal places.) (b) Is the regression coefficient of shoe size statistically significant? (Use a = 0.05.) The regression coefficient of shoe size --Select--- v statistically significant. (c) Does the variable shoe size belong in the model? The variable shoe size -Select--- v belong in the model. (d) Interpret the regression coefficient of Gender. (Round your answer to 3 decimal places). Males are inches taller than females, on average, controlling for shoe size.
