Sex, Foot Length, and Height Refer to Data Set 7 “Foot and Height” in Appendix B and use the sex, foot length, and height of the subjects. Letting the response (y) variable represent sex (0 = female, 1 = male), use the variables of foot length and height to find the multiple regression equation. Use the equation to find the probability that the subject is a male, given that the subject has a foot length of 28 cm and a height of 190 cm.
