Suppose a new standardized test is given to 97 randomly selected

Suppose a new standardized test is given to 97 randomly selected third-grade students in New Jersey. The sample average score Y on the test is 62 points, and the sample standard deviation, sY, is 10 points. The authors plan to administer the test to all third-grade students in New Jersey. The 95% confidence interval for the mean score of all New Jersey third graders is ). (Round your responses to two decimal places.)
