The frequency distribution table for the given histogram will be as follows
| Height | Frequency |
| 63 -66 | 7 |
| 66 - 69 | 6 |
| 69 - 72 | 5 |
| 72 - 75 | 12 |
| 75 - 78 | 16 |
| 78 - 81 | 17 |
| 81 - 84 | 13 |
| 84 - 87 | 10 |
| 87 - 90 | 9 |
| 90 - 93 | 5 |
| 93 - 96 | 1 |
| Total | 101 |
From the table we can find out that class width = Upper limit - Lower limit of any class = 69-66 = 3.
part - 3.
the students less than 78 inches tall = 7+6+5+12+16 = 46
percentage of students less than 78 inches tall = (46/101)*100 = 45.54%
