SAT coaching: 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 is less than 15 points? Let u, represent the mean score after the class and p=H,-u. Use the a = 0.05 level and the P-value method with the TI-84 Plus calculator.
