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?
