Short Answer

A test of mathematical ability is given to a random sample of 10 eighth-grade students before and after they complete a semester-long basic mathematics course. The mean score before the course was 119.60, and after the course the mean score was 130.80. The standard deviation of the difference is 16.061. Test the hypothesis that scores were higher after the course at = .05 using a t test.
