The answer is 4x that the answer
Using the shell method, the volume is
Each cylindrical shell has radius (the horizontal distance from the axis of revolution to the curve ); has height (the vertical distance between a point on the -axis in and the curve ).
Compute the integral.
Since the sample size is too small (n = 9, which is less than 10) we cannot use the normal model to describe the entire population.
Therefore, we expect the sample mean to be different from the population mean.
