Use SAT scores to predict high grade point averages. Use a logistic regression to predict HIGPA using the two SAT scores as explanatory variables.
(a) Summarize the results of the hypothesis test that the coefficients for both explanatory variables are zero.
(b) Give the coefficient for the SAT Math score with a 95% confidence interval. Do the same for the SAT Verbal score.
(c) Summarize your conclusions based on parts (a) and (b).
