42. Approximately 1.5 million high school students take the Scholastic Aptitude Test (SAT)

each year and nearly 80% of the college and universities without open admissions policies use SAT scores in making admission decisions (College Board, March 2006). A sample of SAT scores for the combined math and verbal portions of the test are as follows:

1025 1042 1195 880 945 1102 845 1095 936 790 1097 913 1245 1040 998 998 940 1043 1048 1130 1017 1140 1030 1171 1035

a. Show a frequency distribution and histogram for the SAT scores. Begin the first class with an SAT score of 750 and use a class width of 100.

b. Comment on the shape of the distribution.

c. What other observations can be made about SAT scores based on the tabular and graphical summaries?
