A Comparative Stem-and-Leaf Diagram. In Exercise 6-22, we presented height data that was self-reported by female undergraduate engineering students in a core course at ASU. In the same class, the male students self-reported their heights as follows:

69 67 69 70 65 68 69 70 71 69 66 67 69 75 68 67 68 69 70 71 72 68 69 69 70 71 68 72 69 69 68 69 73 70 73 68 69 71 67 68 65 68 68 69 70 74 71 69 70 69

(a) Construct a comparative stem-and-leaf diagram by listing the stems in the center of the display and then placing the female leaves on the left and the male leaves on the right.

(b) Comment on any important features that you notice in this display.
