Problem A: You're interested in seeing a new movie has just arrived in theaters. There is a linear relationship between audience and critic's scores for similar movies. If the critic's scores have an average of 84 (X= 84), what do you predict the audience score will be if the slope of the regression line is 0.7355 and the Y-axis intercept is 20.5633? Hint: The answer will be between 82 and 83. Problem B: The midterm and final grades in a course are provided below. Given these data, calculate: Question: What is Your Answer Correct Answer is Between: The correlation coefficient 0.70-0.75 The slope of the regression line 0.5-0.6 The Y-axis intercept 40-45 The estimated score on the final 84-86 exam with a midterm score of 83 Data for Problem B ID Midterm (D) Final ()) Cross-Products 35 3025 422: 357: 60 3600 78 6084 4680 70 4900 74 5476 5180 74 5476 90 8100 6660 78 6084 80 6400 5240 80 5400 85 7225 6800 85 7225 95 9025 8075 87 7569 75 5625 6525 90 8100 95 9025 8550 94 8836 90 $100 8460 99 9801 92 8464 9108 92 8464 90 8100 8280 84 7056 78 6084 6552 92 3464 95 9025 8740 1140 95000 1182 100958 97425 Note: A worksheet follows to help organize your calculations.
