Suppose we collect data for a group of students in a statistics class with variables X₁ = hours studied, X₂ = undergrad GPA, and Y = receive an A. We fit a logistic regression and produce estimated coefficient, Bo = -6, B1 = 0.05, and B₂ = 1. (a) Estimate the probability that a student who studies for 40 hours and has an undergrad GPA of 3.5 gets an A in the class. How many hours would the student in part (a) need to study to hav a 50% chance of getting an A in the class?
