Answer #1
The frequency table looks as below
| Potholes | Frequency |
| 1 | 11 |
| 2 | 5 |
| 3 | 6 |
| 4 | 3 |
| 5 | 4 |
| 6 | 2 |
| 7 | 4 |
| Total | 35 |
The relative frequency table looks as below. The relative frequencies are obtained by dividing respective frequencies by the total 35
| Potholes | Frequency | Relative Frequency |
| 1 | 11 | 0.3143 |
| 2 | 5 | 0.1429 |
| 3 | 6 | 0.1714 |
| 4 | 3 | 0.0857 |
| 5 | 4 | 0.1143 |

a) Use statistical software to construct a relative frequency
histogram. Use 32 as the lowest class limit and a class width of 2.
Plot and label the statistics x̄ (x-bar), x̄+1, x̄+2, x̄+3. Draw a
normal density curve on the relative frequency histogram. Comment
on the shape of the distribution.
b) Do you think the normal density curve accurately describes

Record the data.
In class, randomly pick one person. On the class list, mark
that person’s name. Move down four names on the class list. Mark
that person’s name. Continue doing this until you have marked 12
names. You may need to go back to the start of the list. For each
marked name record the five data values. You now have a total of 60
data values.
For each name marked, record the data.
