Math SAT Scores (Raw Data, Software Required): Suppose the national mean SAT score in mathematics is 510. The scores from a random sample of 40 graduates from Stevens High are given in the table below. Use this data to test the claim that the mean SAT score for all Stevens High graduates is the same as the national average. Test this claim at the 0.05 significance level. (a) What type of test is this? O This is a two-tailed test. O This is a left-tailed test. - This is a right-tailed test. DATA (n = 40 ) MATH SAT Scores 494 513 532 (b) What is the test statistic? Round your answer to 2 decimal places. t; = 496 444 402 503 477 (c) Use software to get the P-value of the test statistic. Round to 4 decimal places.
