Assume that in a political science class, the teacher gives a midterm exam and a final exam. Assume that the association between midterm and final scores is linear. Here is the linear model for predicting the final exam score from the midterm score: Predicted final exam score = -15.2 + 12 x midterm score. The coefficient of determination(R?) of the model is 82 81%%, How do you interpret RT in the context of the study? Select one: O a. 82.81% of the variation in the final exam score is explained by the midterm score. O b. 68.57% of the variation in the midterm score is explained by the final exam score. O c. 82.81%% of the variation in the midterm score is explained by the final exam score. O d. 91%% of the variation in the final exam score is explained by the micherm score
