(a)
To construct: A back-to-back stem-and-leaf plot
(a)
Answer to Problem 11RE
Theback-to-back stem-and-leaf plot is constructed
Explanation of Solution
Calculation:
To construct the stem-and-leaf plot, the data needs to be sorted.
The sorted data is tabulated below.
Royalty | President |
The highest stem is
Royalty | President | |
Leaf | Stem | Leaf |
5 2 | 1 | |
8 | 2 | |
5 3 2 | 3 | |
9 9 9 8 3 2 1 0 0 | 4 | 6 9 |
9 8 8 6 6 5 4 2 1 | 5 | 6 6 7 7 8 |
9 8 8 7 7 7 7 5 4 | 6 | 0 0 3 3 4 4 5 6 7 7 7 8 |
7 6 1 0 | 7 | 0 1 1 2 3 4 7 8 8 9 |
1 1 | 8 | 0 1 3 5 8 |
9 | 0 0 3 3 | |
In this means |
Hence, the back-to-back stem-and-leaf plot is constructed.
Conclusion:
Therefore, the back-to-back stem-and-leaf plot is constructed
(b)
To construct: The back-to-back stem-and-leaf plot with split stems
(b)
Answer to Problem 11RE
The back-to-back stem-and-leaf plot with split stems is constructed
Explanation of Solution
The back-to-back stem and leaf display data is followed as
Royalty | President | |
Leaf | Stem | Leaf |
1 | 2 | |
1 | 5 | |
2 | ||
2 | 8 | |
3 | 2 3 | |
3 | 5 | |
4 | 0 0 1 2 3 | |
9 6 | 4 | 6 8 9 9 9 |
5 | 1 2 4 | |
8 7 7 6 6 | 5 | 5 6 6 8 8 9 |
4 4 3 3 0 0 | 6 | 4 |
9 7 7 7 6 5 | 6 | 5 7 7 7 7 8 8 9 |
4 3 2 1 1 0 | 7 | 0 1 |
9 8 8 7 | 7 | 6 7 |
3 1 0 | 8 | 1 1 |
8 5 | 8 | |
3 30 0 | 9 | |
In this |
Hence, the back-to-back stem-and-leaf plot with split stems is constructed.
Conclusion:
Therefore,the back-to-back stem-and-leaf plot with split stems is constructed
(c)
To find: The more appropriate data
(c)
Answer to Problem 11RE
The more appropriate data is stem and leaf plot part b
Explanation of Solution
Calculation:
The more appropriate data is stem and leaf plot part b.
Hence, the more appropriate data is stem and leaf plot part b.
Conclusion:
Therefore, the more appropriate data is stem and leaf plot part b
