we used a computer to generate 1,000 samples, each containing n = 11 observations, from a uniform distribution over the interval from 150 to 200. For this exercise, use a computer to generate 500 samples, each containing n = 15 observations, from this population.

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

b. Repeat part a for the sample median. Compare this approximate sampling distribution with the approximate sampling distribution of x found in part a.
