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 resc poncowunu uen whose parents had attained a higher level of education would on average score higher on the SAT. The overall mean SAT math score was 514.t 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.

population mean math score of students whose parents are college graduates with a bachelor's degree and u, = population mean math score of
students whose parents are high school graduates but do not have a college degree.) For purposes of this study, assume the population variances are unequal when conducting the t-test.
