In order to ensure that there is not a large disparity in the quality of education at various schools in a school district, the school board wants to make sure that the variance of the mean standardized-test scores for all students at each school in the district is less than 66. To test this claim, they looked at the mean student scores for the standardized test from a random sample of 1313 schools in the district. The results from the survey found that the overall mean was a score of 215.290215.290 with a standard deviation of 1.2601.260. With =0.025=0.025, perform a hypothesis test to determine if the variance is less than 66. Assume that the district standardized-test scores are normally distributed.
