Homework Help: Discrete Mathematics

Posted by Joy on Tuesday, July 30, 2013 at 3:51am.

A tutor website wants to see how time spent studying for its content exams affects the ultimate scores. It asked its finite math test takers how much time they spent studying for the exam and compared that data against the final scores out of 60 points. It came up with the linear regression model y = 1.2x + 3 from a sample of 100 test takers with a correlation coefficient of 0.92. What percent of the variation in test scores can be explained by the relationship between hours spent studying and the test scores?
