ne students took the SAT test twice without doing any sort of preparatory course between the two tests. Their scores are listed below. Use the data to test the claim that in the population of all such students, the differences between the scores have mean 0. Student A B C D E F G H I First score 480 510 530 540 550 560 600 620 660 Second score 460 500 530 520 580 590 560 640 690 a. Define the parameter A. mu Subscript d Baseline equals Mean of the first score B. mu Subscript d Baseline equals Mean of the second score C. mu equals Mean score D. mu Subscript d Baseline equals Mean of (First score - Second score) b. State the null and alternative hypotheses A. Upper H 0 : mu Subscript d Baseline equals 0 Upper H 1 : mu Subscript d Baseline greater than 0 B.

Do not reject Upper H 0 B. Reject Upper H 0 e. State the final conclusion A. There is not sufficient sample evidence to support the claim. B. There is not sufficient evidence to warrant rejection of the claim. C. There is sufficient evidence to warrant rejection of the claim. D. The sample data support the claim. f.
