Suppose we collect data for a group of students in a data mining class with variables X1 =hours studied, X2 =undergrad GPA, and Y= receive an A. We fit a logistic regression and produce estimated coefficients, 0 =6, 1 = 0.05, 2 = 1. (a) Estimate the probability that a student who studies for 40 h and has an undergrad GPA of 3.5 gets an A in the class.

(b) How many hours would the student in part (a) need to study to have a 2 to 1 odds of not getting an A in the class?
