A certain test preparation course is designed to improve
students' SAT Math scores. The students who took the prep course
have a mean SAT Math score of 504 with a standard deviation of
38.5, while the students who did not take the prep course have a
mean SAT Math score of 492 with a standard deviation of 43.5. The
SAT Math scores are taken for a sample of 78 students who took the
prep course and a sample of 85 students who did not take the prep
course. Conduct a hypothesis test of the claim that the SAT Math
scores for students who took the prep course is higher than the SAT
Math scores for students who did not take the prep course.
