You may need to use the appropriate appendix table or technology to answer this question.

Consider the following hypothesis test.

H0: μ1 − μ2 = 0

Ha: μ1 − μ2 ≠ 0

The following results are for two independent samples taken from the two populations.

Sample 1 Sample 2

n1 = 70

n2 = 60

x1 = 102

x2 = 104

σ1 = 8.6

σ2 = 7.9

(a) What is the value of the test statistic?

(b) What is the p-value?

(c) With α = 0.05, what is your hypothesis testing conclusion?

You may need to use the appropriate technology to answer this question. 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...
