Question: Suppose you administer a certain aptitude test to a random sample of 9 students in your high school, and the average score is 105. We want to determine the mean μ of the population of all students in the school. Assume a standard deviation of σ = 15 for the test. Round all answers to 2 decimals.

Write a sentence explaining the 98% confidence interval in context of the question. (There are only a few ways to do this correctly, so be sure to read the book closely.)
