Suppose we have collected the midterm and final scores of 200 students in a Statistics class, and we observed that the scatter plot of final scores versus midterm scores is roughly linear. Suppose the average midterm score is 76, with SD 12, and the average final score is 71, with SD 10. Suppose the correlation coefficient between midterm and final scores is 0.6.
Use the regression line, or an equivalent regression procedure, to predict the final score for someone who got 83 on the Midterm.

9. A lot of corn grows in Iowa. For several years, farmers have kept track of the amount of rainfall (in inches) and the amount of corn produced (in bushels per acre). A strong and linear relationship has been observed between these variables. When a regression equation is constructed in order to predict amount of corn produced based on rainfall, it is found that the equation has an intercept of 89.54 and a slope of 0.13. We can conclude from...
