Optional Review Problem

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.

College Grads 485 487 550 549 666 526 538 426 534 531 556 562 497 432 608 485

High School Grads 442 492 580 478 479 425 486 485 528 390 524 535

(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. (Let₁= populationmean verbal score of students whose parents are college graduates with a bachelor's degree and₂= populationmean verbal score of students whose parents are high school graduates but do not have a college degree.)

H₀:₁₂0

H_a:₁₂= 0

H₀:₁₂< 0

H_a:₁₂= 0

H₀:₁₂= 0

H_a:₁₂0

H₀:₁₂0

H_a:₁₂> 0

H₀:₁₂0

H_a:₁₂< 0

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

p-value =

(d)

At= 0.05,

what is your conclusion?

Do not rejectH₀. There is insufficient evidence to conclude that higher population mean verbal scores are associated with students whose parents are college graduates.

RejectH₀. There is sufficient evidence to conclude that higher population mean verbal scores are associated with students whose parents are college graduates.

Do not RejectH₀. There is sufficient evidence to conclude that higher population mean verbal scores are associated with students whose parents are college graduates.

RejectH₀. There is insufficient evidence to conclude that higher population mean verbal scores are associated with students whose parents are college graduates.
