A simple random sample is taken of 35 second-graders in a certain school district who were given a standardized mathematics skills test. The sample produces an average score of 49.7 and a standard deviation of 15.4. The nationwide score on this test is a 50. The superintendent wants to know whether second-graders in the district have lower math skills than the nationwide average. Test at 5% level of significance.

![A simple random sample is taken of 35 second-graders in a certain school district who were given a
standardized mathematics skills test. The sample produces an average score of 49.7 and a standard
deviation of 15.4. The nationwide score on this test is a 50. The superintendent wants to know whether
second-graders in the district have lower math skills than the nationwide average. Test at 5% level of
significance.
