Construct a stem and leaf diagram, a frequency histogram, and a relative frequency histogram for the following data set. For the histograms use classes 6.0–6.9, 7.0–7.9, and so on. 8.5 8.2 7 7 4.9 6.5 8.2 7.6 1.5 9.2 9.3 9.6 8.5 8.8 8.5 8.7 8 7.7 2.9 6.9

0 | 3 8

1  | 2 2 4

2 | 0 1 3 6

3 | 4

Step-by-step explanation:

The first row is for numbers 0-9, the second row is for numbers 10-19, the third row is for numbers 20-29, and the fourth row is for numbers 30-39. The first column indicates the tens and the second column indicates the ones. Notice that 12 appears twice in the list and in the stem and leaf diagram. This diagram allows us to easily see the distribution of the data.
