A driving instructor is investigating whether the time a driver spends in a driver’s education course improves their score on the driver’s test. The instructor randomly selected 10 drivers from a driver’s education course and recorded the number of hours each driver attended the driver’s education course and their corresponding score on the driver’s test. Assuming all conditions for inference are met, which of the following significance tests should be used for the investigation? A. A chi-square test of independence B. A two-sample t-test for a difference between means C. A two-sample z-test for a difference between proportions D. A linear regression t-test for slope E. A matched pairs t-test for a mean difference
