X = Hours Y = Score on Physical XY ExercisefWeek Fitness Test 8 10 6 3 4 5 2 2 l 1 Sum 1) Fill in the chart. 2) Plot each pair of scores on the graph paper provided. 3) Draw the regression line. 4) Calculate the e_xpected Performance Score for a hypothetical person (not one of the actual scores shown) who had 5 hours of exercise each week. 5) Calculate the error of prediction for the person who had 6 hours of exercise 6) Using the formulas below, calculate h (the slope of the regression line). 7) Using the formulas below, calculate a (the y intersect of the regression line). 8) Plugging the values for z_1_and h into the third equation below, calculate the predicted (or expected Performance Score (Fitness) for someone who scored 8 on the Exercise Column, where Y' is the Y score predicted from the X score, b is the slope of the line, and a is where it intersects the Y axis. b = a = Y' = bX + a 9) What is the error of prediction for that person? 10) Calculate all the errors of prediction and divide by n (5) to obtain the standard error of measurement
