A manager at a local discount gym believes that less than 20% of gym members use the gym, at least 5 days a week. She randomly selects 100 gym members and tracks (using the electronic login system at the door) how many days they used the gym over the 2-week period. The following are the results:
| 2 | 3 | 10 | 4 | 2 | 3 | 8 | 4 | 8 | 10 |
| 5 | 0 | 6 | 3 | 9 | 13 | 6 | 3 | 12 | 5 |
