Refer to Exercise 2.21, which contains data on the amount of money donated to charity by the top 40 donors in the 2010 Slate 60. Here are the amounts rounded to the nearest million dollars

 

332	279	163	120	118	117	110	101	101	100
100	88	84	80	67	62	59	53	50	50
50	50	49	45	42	41	40	39	35	33
32	32	30	30	30	30	30	29	28	27

 

 

 

a. Prepare a stem-and-leaf display for the data. The stems should consist of the hundreds digits, and the leaves should consist of the tens and ones digits (e.g., for the number 117, the stem would be 1 and the leaf would be 17, while for the number 41, the stem would be 0 and the leaf would be 41). Arrange the leaves for each stem in increasing order.

b. Prepare a split stem-and-leaf display for the data. Split each stem into two parts. The first part should contain the leaves with 0, 1, 2, 3, and 4 in the tens place, and the second part should contains the leaves with 5, 6, 7, 8, and 9 in the tens place.

c. Which display (the one in part a or the one in part b) provides a better representation of the features of the distribution? Explain why you believe this.
