Question

Suppose a random survey was taken in a large urban high school to determine if vending machine location affects whether sports drinks are more likely to be purchased. A single large sample size of n = 500 was taken over the last year. In the cafeteria, 78 of the 165 drinks purchased were sports drinks. In the gym, 98 of the 157 drinks purchased were sports drinks, and in the auditorium, 54 of the 178 drinks purchased were sports drinks. Select the appropriate Ho and Ha for the hypothesis test to determine whether a relationship exists between location and drink preference.
