Suppose that you wanted to predict the final exam scores based on the midterm score. You found that the average final exam score was 78 and average midterm score was 75. The standard deviation for the final exam was 5.4 and the standard deviation for the miderm score was 6.7. The correlation coefficient was 0.86. Find the least squares regression line. y yat =26.025+0.693x y hat =1.067x−2.025 y hat =26.025x+0.693 y hat =1.067+2.025x
