Consider the following data. Calculate mean and standard deviation for each test (can you see it is test-retest situation?). Then find the regression equation of Final scores on Midterm scores. Predict the final scores for two students . For one who received 72 on Midterm . For one who received 90 on Midterm Draw a scatterplot Comment how the regression effect manifest itself here. and the regression line; mark the two points (for x=72 and x=90).
