The following data are available for a simple linear regression analysis attempting to link hours of training (x) to hourly output (y). In applying the least squares criterion, the slope (b) and the intercept (a) for the best-fitting line are b = 2.4 and a = 3.6.Compute the value of r, the correlation coefficient here.
