Another 503 students are selected at random from Florida. They are given a 3-hour preparation course before the test is administered. Their average score is 1019, with a standard deviation of 95. Suppose we want to test whether students in taking the 3-hour preparation course perform differently as the students who did not take the preparation course by testing the following hypothesis: H0: E(YFL, Prep) – E(YFL, NoPrep) = 0 vs H1: E(YFL, Prep) – E(YFL, NoPrep) ≠ 0Construct a 95% confidence interval for the change in average test score
associated with the prep course.
