Question: Approximately 1.65 million high school students take the Scholastic Aptitude Test (SAT) each year, and nearly 80 percent of the college and universities without open admissions policies use SAT scores in making admission decisions. The current version of the SAT includes three parts: reading comprehension, mathematics, and writing. A perfect combined score for all three parts is 2400. A sample of SAT scores for the combined three-part SAT are as follows:

a. Show a frequency distribution and histogram. Begin with the first bin starting at 800, and use a bin width of 200.

b. Comment on the shape of the distribution.

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