The confidence interval based on a one step mestimator

Reference no: EM131397163

For the data in the previous exercise, verify that the 0.95 confidence interval for the 20% trimmed mean returned by the R function trimpb is (7.25, 63). Why would you expect this confidence interval to be substantially longer than the confidence interval based on a one-step Mestimator?
