For the sample data, compute the mean and its standard error (from the standard deviation), and the median. b. Using R, compute bootstrap estimates of the mean, median and 25% trimmed mean with estimates of their standard errors, using B = 1000 resamples. (Use set. seed(1) to allow your results to be reproduced.) c. Compare parts a and b. How do the estimates compare?
