Regression Analysis

For the y and x values listed in file XR15066, obtain the simple linear regression equation, then analyze the residuals by (a) constructing a histogram, (b) using a normal probability plot, (c) plotting the residuals versus the x values and (d) plotting the residuals versus the order in which they were observed. Do any of the assumptions of the simple linear regression model appear to have been violated?
