You have obtained their overall grade average. Child No. Hours of TV Overall Grade Average 1 5 80 2 20 67 3 6 75 4 14 70 5 12 80 a. Calculate the correlation between hours of television watched and overall grade average. Interpret the correlation - what does it mean? b. Calculate the regression equation (use television watching to predict grade). c. Make a scatter plot of the data and draw the line of best fit on your scatter plot.
