Question 1

◦

runs test.
Question 2
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). What is the null hypothesis?
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 |
|
◦
H0: The median amount of water consumed by the team is equal to 30 L.
◦
H0: The mean amount of water consumed by the team is equal to 30 L.
◦
H0: The median amount of water consumed by the team is less than 30 L.
◦
H0: The mean amount of water consumed by the team is less than 30 L.
