Use the population of ages {56, 49, 58, 46} of the four U.S. presidents (Lincoln, Garfield, McKinley, Kennedy) when they were assassinated in office. Assume that random samples of size n = 2 are selected with replacement. 1. List the 16 different samples. For example, the samples for age 56 would be 56, 56 56, 49 56, 58 56, 46. 2. After listing all 16 samples, find the mean of each sample, then construct a table representing the sampling distribution...
