3. A statistical analysis is made of the midterm and final scores in a large course, with the following results: (20 points) Average midterm score = 65, SD = 10, Average final score = 65, SD = 12, r = 0.6 The scatter diagram is football shaped. a. About what percentage of the class final scores above 70? ((5 points) b. A student midterm was 75. Predict his final score (5 points) c. Suppose the percentile rank of midterm score was 95%, predict his percentile rank on the final score (5 points). d. Of those whose midterm score was 70, about what percentage of final scores over 80? (5 points)
