Question

(b) make another stemplot of the data by splitting stems.

Explanation:

Step1: Identify stem - leaf concept

In a stemplot, the stem represents the leading digit(s) and the leaf represents the trailing digit. Splitting stems means having two rows for each stem value. For example, for single - digit numbers, if we split stems, we will have one row for leaves 0 - 4 and another for leaves 5 - 9.

Step2: Analyze given data

The data values seem to be two - digit numbers. We group them by the tens digit (stem) and the units digit (leaf).

Step3: Fill the stemplot

Starting from the lowest stem value. For the stem value of 0, we have leaves 5, 6, 7, 7, 8, 8, 9. For the stem value of 1, we have leaves 0, 0, 0, 1, 2, 3, 4. For the stem value of 2, we have leaves 5, 5, 6, 6, 8, 8, 8, 8. For the stem value of 3, we have leaves 5, 6, 9, 9. For the stem value of 4, we have leaves 5, 5, 7, 9.
The stemplot (from top - to - bottom, left - to - right) will be filled as follows:
0 | 5 6 7 7 8 8 9
1 | 0 0 0 1 2 3 4
2 | 5 5 6 6 8 8 8 8
3 | 5 6 9 9
4 | 5 5 7 9

Answer:

The filled stemplot is:
0 | 5 6 7 7 8 8 9
1 | 0 0 0 1 2 3 4
2 | 5 5 6 6 8 8 8 8
3 | 5 6 9 9
4 | 5 5 7 9
