1. For the observations
21, 36, 42, 24, 25, 36, 35, 49, 32
verify that the sample mean, trimmed mean, and median are X‾= 33.33, X‾t = 32.9, and M = 35.
2. The largest observation in given Exercise is 49. If 49 is replaced by the value 200, verify that the sample mean is now X‾= 50.1 but the trimmed mean and median are not changed. What does this illustrate about the resistance of the sample mean?
