A general chemistry class with 31 students took an exam, resulting in an average score of 72 with a standard deviation of 10. If another general chemistry class, with only 20 students, took the same exam, resulting in an average score of 75 with a standard deviation of 8, were the scores statistically different at the 95% confidence level?
