5.11 Use the computer to generate 500 samples, each containing n = 25 measurements, from a population that contains values of xequalto1,2,...,48, 49, 50. Assume that these values of x are equally likely. Calculate the sample mean and median m for each sample. Construct relative frequency histograms for the 500 values of and the 500 values of m. Use these approximations to the sampling distributions of and m to answer the following questions: a. Does it appear that Z and m are unbiased estimators of the population mean? [Note: i = 25.5.] b. Which sampling distribution displays greater variation
