Instructions Read the scenario below, and answer the next 2 questions that follow based on this scenario. Scenario A high school science teacher conducted a randomized experiment to compare the effectiveness of two study methods—Method A (traditional note-taking) and Method B (using flashcards)—in preparing students for their final exam. The students were randomly assigned to one of the two methods, and they followed their assigned study routine for two weeks. At the end of the experiment, the average exam score for students using Method A was 85%, while the average exam score for students using Method B was 82%. The teacher wants to determine whether the difference in exam scores is statistically significant or could have occurred by chance.
