A sample of 10 students took a class designed to improve their SAT math scores. Following are their scores before and after the class. Can you conclude that the mean increase in scores differs from 15 points? Let μ1 represent the mean score after the class and μd=μ1-μ2. Use the =α0.05 level and the P-value method with the TI-84 Plus calculator.
