###### Question:

olo SAT coaching: A sample of 10 students took a class designed to improve their SAT math scores. Following are their scores before and after the class. Can you conclude that the mean increase in scores is greater than 15 points? Let , represent the mean score after the class and Md = H, -Hz. Use the a=0.01 level and the P-value method with the TI-84 Plus calculator. Score Before 451 453 526 440 After 529 466 447 440 439 435 491 473 482 479 451 431 454 463 511 493 Send data to Excel Part 1 of 4 (a) State the appropriate null and alternate hypotheses. HO: M = 15 H: M, >15 This is a right-tailed test. Part: 1/4 Part 2 of 4 (b) Compute the P-value. Round the answer to at least four decimal places. P-value = 0.8869 х 5
