Answer to Problem 69E
The option (a) is the best one.
Explanation of Solution
Given:
50, 55, 0, 97, 76, 0, 0, 87, 25, 65
(a) 0,1,2, 5,4, 5,6,7,8,9
(b)0,2, 5, 5,6,7,8,9.
(c)0, 5, 5,6,7.
(d)00, 10, 20, 50,40, 50,60,70, 80,90.
(c) None of these.
Calculation:
The amount of money (cents) in coins carried by 10 students in statistics class: 50, 35, 0, 97, 76, 0, 0, 87, 23, 65.
Using Excel, the stem and leaf output for the data is given below:
Stem unit = 10
Leaf unit = 1
Stem | Leaf |
0 | 000 |
1 | |
2 | 3 |
3 | 5 |
4 | |
5 | 0 |
6 | 5 |
7 | 6 |
8 | 7 |
9 | 7 |
From the output the generalized steam is 0,1,2,3,4,5,6,7,8.9.
So the stem plot becomes
(a) 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Conclusion:
Thus, the option (a) is the best one.
