An athletic trainer is concerned that his athletes are not drinking enough water during games. He randomly samples 11 previous games with comparable temperature and humidity and records the amount of water consumed by the team in liters (shown in the table). Conduct a sign test to see if the median amount of water consumed exceeds 30 L. (Assume that the amount of water consumed per game is a continuous variable.)
Amount of Water Consumed per Game (in liters)
| 21.2 | 32 | 21.5 |
| 30 | 25.5 | 28 |
| 35.5 | 40 | 22.7 |
| 29.2 | 22.5 |
