Chapter 10.2, Problem 16E

Effect of Parents’ Education on Student SAT Scores. The College Board provided comparisons of Scholastic Aptitude Test (SAT) scores based on the highest level of education attained by the test taker’s parents. A research hypothesis was that students whose parents had attained a higher level of education would on aver age score higher on the SAT. The overall mean SAT math score was 514. SAT math scores for independent samples of students follow. The first sample shows the SAT math test scores for students whose parents are college graduates with a bachelor’s degree. The second sample shows the SAT math test scores for students whose parents are high school graduates but do not have a college degree.

1. a. Formulate the hypotheses that can be used to determine whether the sample data support the hypothesis that students show a higher population mean math score on the SAT if their parents attained a higher level of education.
2. b. What is the point estimate of the difference between the means for the two populations?
3. c. Compute the p-value for the hypothesis test.
4. d. At α = .05, what is your conclusion?
