Are you smarter than a second-grader? A random sample of $1 second-graders in a certain school district are given a standardized mathematics skills test. The sample mean score is x = 44. Assume the standard deviation of test scores is o = 15. The nationwide average score on this test is 50. The school superintendent wants to know whether the second-graders in her school district have different math skills from the nationwide average. Use the a = 0.01 level of significance and the P-value method with the TI-84 calculator. Part: 0 / 4 Part 1 of 4 State the appropriate null and alternate hypotheses. Ho: M = 50 00 0=0 H: p > 50 This hypothesis test is a right-tailed V test. X 5 Part: 1 / 4 Part 2 of 4 Compute the P-value of the test statistic. Round the answer to at least four decimal places. P-value =
