For example, the curent yearis 20, hen a coln with 2003 stamped on it is 2years old. a. Drav a histogram or cther graph showhng the populetion dsribution. b. Randomly select fve colns and record the mean age of the sampled coirs. Repeat this sampling process 20 times. Now draw a istogram or other graph showing the distrbu- fion of the sample means. C. Compare the shapes of the two histograms.
