An article in Wear (1992, Vol. 152, pp. 171-181) presents data on the fretting wear of mild steel and oil viscosity. Representative data follow with x- oil viscosity and y - wear volume (10 cubic millimeters). y 240 181 193 155 172 110 113 75 94 1.6 94 15.5 20.0 22.0 35.5 43.0 40.5 33.0 Round your answers to two decimal places (e.g. 98.76). (a) Construct a scatter plot of the data. Does a simple linear regression model appear to be plausible? O Yes O No (b) Fit the simple linear regression model using least squares. Find an estimate of o². Bo + B 1x Bo = i (c) Predict fretting wear when viscosityx- 30. (d) Obtain the fitted value of y whenx- 22.0 and calculate the corresponding residual. i e = 2.
