In this problem, we use the CSDATA data set, which is available in 'CSDATA.txt'. We do ne an indicator variable, say HIGPA, to be 1 if the GPA is 3.0 or better and 0 other- wise. Speci cally, we investigate the e ect of gender on the odds of getting a high GPA.
(a).Use gender to predict HIGPA using a logistic regression. Explain the results.
(b). Perform a logistic regression using gender and the two SAT scores to predict HIGPA. Explain the results.
(c).Compare the results of parts (a) and (b) with respect to how gender relates to HIGPA. Summarize your conclusions.
