Appendix B.4 is a table of random numbers that are uniformly distributed. Hence, each digit from 0 to 9 has the same likelihood of occurrence.
a. Draw a graph showing the population distribution of random numbers. What is the population mean?
b. Following are the first 10 rows of five digits from the table of random numbers in Appendix B.4. Assume that these are 10 random samples of five values each. Deter minethe mean of each sample and plot the means on a chart similar to Chart 8–4. Compare the mean of the sampling distribution of the sample mean with the populationmean.
Solution:
