The expected number of study hours for students in a class is 10 hours/week and it is known that the fraction of this class that will receive an A grade is 3/8. Whether a student gets an A grade or not (indicated by a binary variable where 1 indicates that the student will get an A grade and 0 indicates that the student will not get an A grade) is explained by a logistic regression model with the following logit: -23 + 2 * number of study hours + GPA What is the GPA required for getting an A grade in this class given the student spends the expected number of hours studying? (You may need to use one of the following values in your calculation: loge (0.6) = -0.51, loge (0.67) = -0.41, loge (1.5) = 0.41)
