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.
Before 439 451 435 431 451 454 453 463 491 455
After 511 526 529 473 493 440 466 481 482 459
Can you conclude that the mean increase in scores is greater than 15 points? Let u1, represent the mean score after the class and ud = u1-u2. Use the alpha = 0.01 level and the P-value method with the table.
