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 = 0.10 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: H > 50 This hypothesis test is a right-tailed test. X 5Compute the P-value of the test statistic. Round the answer to at least four decimal places. Determine whether to reject H0. (Choose one) V the null hypothesis H0. Summarize the results.
