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 (10-4 cubic millimeters). y 240 181 193| 155 172 110 113 75 94 x 1.6 9.4 15.5 20.0 22.0 35.5 | 43.0 40.5 33.O 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 No
