I think the group 2 survey is likely to be biased towards people who are not too keen on zoos since all the values are small.
From group 1 and 3 the mean number of visits are
(4 + 10 + 6 + 3 + 8 + 7 + 9 + 3 + 4 + 7) / 10
= 61/10
mean = 6
We have 12 8-ounce bottles, so altogether we have 12 * 8 = 96 ounces of bottled water. If it all costs $3.36, than one ounce of bottled water costs $3.36 / 96 = $0,035.
