Are vou smarter than a secondgrader? A random sample of 5:" secondgraders in a certain school district are given a standardized mathematics skills test. The sample mean score is E = 46. Assume the standard deviation of test scores is G = 15. The nationwide average score on this test is 5'3. The school superintendent wants to know whether the second-graders in her school district have weaker math skills than the nationwide average. Use the .11: 0.05 level of signicance and the P-value method with the TI-34 calculator.
