Different samples (c) Compute the mean of the sample means and compare it to the population mean. (Round your answers to 1 decimal place.) The mean of the sample means is The Population mean is Both means are equal. Explanation: a.10 found by 5 C 2 c. μ = (4+3+5+5+3)/5 = 4.0 3. Appendix B.6 is a table of random numbers. Hence, each digit from 0 to 9 has the same likelihood of occurrence. A table of random numbers is given below. Assume that these are 5 random samples of five values each. (b-1) Determine the mean of each sample. (Round your answers to 2 decimal places.) 3 9 6 4 4 5 6 8 7 4 4 4 5 4 7 1 6 7 3 4 7 4 5 7 9 (b-2) Is this an example of the uniform distribution?
