Comment on the strategy of applying the boxplot to the data in Exercise 2, removing any outliers, computing the sample mean for the data that remain, and then estimating the standard error of this sample mean based on the sample variance of the data that remain.

Use results on Winsor zed expected values in Chapter 2 to show that if the error term in Eq. (3.4) is ignored, X t is a Winsor zed unbiased estimate of µt.
