Prоfessоr Leаng wаnts tо see if the scores for the sаme midterm exam are significantly different between two classes. The first class with 21 students has a mean score of 75 with a standard deviation of 10 and the second class with 16 students has a mean score of 80 with a standard deviation of 15. Is there enough evidence to suggest that one class performed better than the other? Test the claim at a 90% confidence level. This problem is an example of what type of hypothesis testing: [ans1] Step 1: State the Claim Ho:
