Exercise 32 (#5.70, #5.71). Obtain the asymptotic relative efficiency of the trimmed sample mean X, (Exercise 21) with respect to (i) the sample mean, based on a random sample of size n from the double exponential distribution with location parameter 0 E R and scale parameter 1; (ii) the sample median, based on a random sample of size n from the Cauchy distribution with location parameter 8 e R and scale parameter 1
