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 greater than 1s points? Let ,
represent the mean score after the class and ,=4,-4. Use the a=0.10 level and
the p-value method with the TI-84 Plus calculator.
