Male and female CS students (optional).
Is there a difference between the average SAT scores of males and females? The CSDATA data set, described in the Data Appendix, gives the Math (SATM) and Verbal (SATV) scores for a group of 224 computer science majors. The variable SEX indicates whether each individual is male or female.
(a) Compare the two distributions graphically, and then use the two-sample t test to compare the average SATM scores of males and females.
Is it appropriate to use the pooled t test for this comparison? Write a brief summary of your results and conclusions that refers to both versions of the t test and to the F test for equality of standard deviations. Also give a 95% con?dence interval for the difference in the means.
(b) Answer part (a) for the SATV scores.
(c) The students in the CSDATA data set were all computer science majors who began college during a particular year. To what extent do you think that your results would generalize to (i) computer science students entering in different years, (ii) computer science majors at othercolleges and universities, and (iii) college students in general?
