Question

Consider the following list of ages

71, 61, 78, 77, 81, 33, 80, 62, 74, 59, 91, 76, 70, 98, 96, 94, 80, 59, 72, 82, 83, 74, 86, 77, 57, 75, 62, 74, 62, 79, 86

(a)

Create a stemplot for the ages using each 10s value twice instead of once on the stem. (Enter numbers from smallest to largest separated by spaces. Enter NONE for stems with no values.)

Answer 1

Solution:

For constructing the stem and leaf chart, we need to arrange all values in an increasing order. Also, we create stem plot for the ages using each 10s value twice instead of once on the stem. Data in an increasing order is given as below:

X
33
57
59
59
61
62
62
62
70
71
72
74
74
74
75
76
77
77
78
79
80
80
81
82
83
86
86
91
94
96
98

The required stem and leaf plot is given as below:

Stem	Leaves
3	3
3	NONE
4	NONE
4	NONE
5	NONE
5	7,9,9
6	1,2,2,2
6	NONE
7	0,1,2,4,4,4
7	5,6,7,7,8,9
8	0,0,1,2,3
8	6,6
9	1,4
9	6,8
