The teacher randomly assigns 40 students to use the app for two weeks and 40 different students to use traditional worksheets for two weeks. Afterward, all students take the same vocabulary quiz, and the response variable is the quiz score (0–100). The teacher wants to test whether the mean score differs between the two groups. Which inference procedure is most appropriate?
