Are you smarter than a second grader? A random sample of second graders in a certain school district are given a standardized mathematics skills test. The sample mean score is . Assume the standard deviation of test scores is . The nationwide average score on this test is . The school superintendent wants to know whether the second graders in her school district have different math skills than the nationwide average. Use the level of significance and the -value method with the TI-84 Plus calculator. Part: 0 / 5 0 of 5 Parts Complete Part 1 of 5 (a) State the appropriate null and alternate hypotheses. This hypothesis test is a test.

Are you smarter than a second-grader? A random sample of 55 second-graders in a certain school district are given a standardized mathematics skills test. The sample mean score is x = 46. Assume the standard deviation of test scores is σ = 18. 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 α = 0.05 level of significance and the P-value method with the TI-84 calculator. 1. State the appropriate null and alternate hypotheses: H0: μ = 50, H1: μ ≠ 50 This hypothesis test is a two-tailed test. 2. p-value 3. Does it reject?

Are you smarter than a second-grader? A random sample of 61 second-graders in a certain school district are given a standardized mathematics skills test. The sample mean score is x = 45. Assume the standard deviation of test scores is σ = 20. The nationwide average score on this test is 50. The school superintendent wants to know whether the second-graders in her school district have weaker math skills than the nationwide average. Use the α = 0.01 level of significance and the P-value method with the TI-84 calculator. State the appropriate null and alternate hypotheses. 1. H0: μ = 50, H1: μ < 50 This hypothesis test is a one-tailed test. 2. p-value? 3. Does it reject or not reject?
