Answer to Problem 50E
The distribution of I-AAA is more symmetric as compare to V-AA.
Explanation of Solution
The comparative stem-plot shows that the distribution of I-AAA is more symmetric as compare to V-AA. There is only one peak in 1-AAA distribution. It has single peak and is called unimodal. Distribution V-AA has asymmetric distribution. It has two peaks and is a bimodal.
