Consider a population that contains values of x equal to 00, 01, 02, 03,c, 96, 97, 98, 99. Assume that these values occur with equal probability. Use the computer to generate 500 samples, each containing n = 20 measurements, from this population. Calculate the sample mean x and sample variance s2 for each of the 500 samples.

a. To approximate the sampling distribution of x, construct a relative frequency histogram for the 500 values of x.

b. Repeat part a for the 500 values of s2.
