Suppose we have a dataset for a group of 50 adults, showing the number of teeth each person has:
| Number of teeth | Count |
|---|---|
0 |
5 |
22 |
1 |
26 |
1 |
27 |
1 |
28 |
4 |
29 |
3 |
30 |
5 |
31 |
3 |
32 |
27 |
Draw a histogram for the table in the space below. For each row, find which interval (or “bin”) on the x-axis represents the right number of teeth. Then fill in the box so that the height of the box is equal to the sum of the counts that fit into that interval. One of the intervals has been completed for you.
