In an introductory stats course x = midterm score and y = final exam score. The midterm score had a mean of 75 and a standard deviation of 4. The final exam score had a mean of 83 and a standard deviation of 9. The correlation between exam scores is 0.45 Find the regression equation. What would be the final exam would be if one scored a 67 on the midterm? Assume midterm scores predict final exam scores. Round your answer to the nearest whole number.
