An educator is interested to test whether the SAT preparatory course is effective in raising the SAT scores. A simple random sample of 7 students took SAT, and their scores are recorded below. The same students took SAT after the preparatory course. At 5% significance level, is there an increase in SAT scores after the preparatory course? Assume that both distributions of SAT scores before and after the preparatory course are normal. Find the corresponding p-value (use a calculator)
