Run the CHISQUARE program for each sample size and degrees of freedom listed below; use a population mean of 0, standard deviation of 1, and 250 repli-cations. Graph the shape of the distributions and list the modal group. The modal group is the group with the highest relative frequency.

a. Does the shape of the chi-square distribution change as sample size increases? YES ______ NO ________

b. List the modal group values from the graphs in the table. The mode of the theoretical chi-square distribution is (DF − 2) when DF > 2. List the theoretical chi-square mode for each sample size. (ERROR = MODAL GROUP − TRUE MODE)
