Extracted text: Are you smarter than a second-grader? A random sample of 51 second-graders in a certain school district are given a standardized mathematics skills test. The sample mean score isx-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. H OO H This hypothesis test is a (Choose one) left-tailed right-taled two-tailed test.
