Are you smarter than a second-grader? A random sample of 60 second-graders in a certain school district are given a standardized mathematics skills test. The sample mean score is =x55. Assume the standard deviation of test scores is =σ9. The nationwide average score on this test is 53. The school superintendent wants to know whether the second-graders in her school district have different math skills than the nationwide average. Use the =α0.10 level of significance and the P-value method with the table. Find the P-value. Round the answer to at least four decimal places.
