In a study to determine whether or not listening to classical music has a positive effect on math performance, 100 students were randomly assigned to two groups. Both groups received the same instruction in mathematics from the same teacher. One group listened to classical music while studying and the other group studied in silence. Both groups were then administered the same 50 point exam. Which of the following procedures would be most appropriate for determining which studying environment was more effective in increasing math performance? (A) A t-test for the slope of the regression line. (B) A matched pairs t-test. (C) A two-sample z-test for proportions. (D) A two-sample t-test for means. (E) A chi-square test for independence.
