A math teacher wants to determine if a new book proposed for the course will yield different results than the old book that was used before. The math teacher decided that 2 classes have different math ability coming into the course. He gives a test at the beginning of the semester to measure the math ability the students have when they come into the course. He uses the test to see if there is a difference between the 2 books. Old Book: 97, 94, 94, 95, 90, 91, 90, 85, 87, 92, 85, 81, 89, 83, 85, 80

New Book: 96, 95, 94, 92, 92, 90, 90, 89, 88, 88, 86, 86, 84, 84, 84, 83

Perform a significance test at the 1% level to see if the scores show a difference in the student's math ability.
