Dave carried out a study on workout habits at a local fitness centre. He wanted to investigate whether male or female gym-goers are more likely to prefer morning workouts over evening workouts. He approached the first 25 male and 25 female gym-goers who were available in the reception lobby during a Wednesday lunch break and asked them to state their preference.
Table 1 shows the number of male and female gym-goers who preferred morning or evening workouts.
| Male | Female | |
|---|---|---|
| Prefer morning workouts | 17 | 8 |
| Prefer evening workouts | 8 | 17 |
