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 average 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.

 485 503 534 549 650 510 570 426 550 499 588 594 481 464 576 469
 442 492 580 478 479 425 486 485 528 390 524 535

b) What is the point estimate of the difference between the means for the two populations?

c) Find the value of the test statistic. (Round your answer to three decimal places.)

Compute the p-value for the hypothesis test. (Round your answer to four decimal places.)

d) At α = 0.05, what is your conclusion?

Do not Reject H0. There is sufficient evidence to conclude that higher population mean math scores are associated with students whose parents are college graduates.

Reject H0. There is sufficient evidence to conclude that higher population mean math scores are associated with students whose parents are college graduates.

Reject H0. There is insufficient evidence to conclude that higher population mean math scores are associated with students whose parents are college graduates.
