Run the CHISQUARE program again for the following sample sizes, but use a population mean of 10, standard deviation of 4, and 250 replications. Graph the shape of the distributions and list the range of the chi-square values. The range is the maximum minus the minimum chi-square value.

a. Compare these graphs with those in Exercise 1. What differences do you see?

b. The variance of the theoretical chi-square distribution is two times the degrees of freedom (2*df). List the theoretical chi-square variance and standard devi-ation. Divide the range of the chi-square values by four (Range/4) to approxi-mate the standard deviation of the simulated chi-square distribution. (ERROR = APPROXIMATE STANDARD DEVIATION − THEORETICAL STANDARD DEVIATION)

c. Does the theoretical standard deviation compare to the estimated standard deviation? YES ________ NO _______
