Question

Appendix B.4 is a table of random numbers that are uniformly distributed. Hence, each digit from 0 through (including) 9 has the same likelihood of occurrence. (Round your answers to 2 decimal places.)

1. Compute the population mean and standard deviation of the uniform distribution of random numbers.

2. Assume that 10 random samples of five values are selected from a table of random numbers. The results follow. Each row represents a random sample.
   

9	1	6	1	2
6	7	1	4	0
0	1	2	7	7
5	2	1	3	1
3	0	2	1	7
9	5	2	8	3
5	1	8	4	4
5	8	9	2	8
2	9	9	9	4
5	6	9	9	8

Compute the mean of each sample.

3. Compute the mean and standard deviation of the sample means. Compare the values to the population mean and standard deviation.
