points get the flu vaccine, after all, the colleges and universities are constantly offering incentives such as free food, gift cards, etc.
| You decide to conduct a brief survey in your dorm building. In a random sample of 30 student who live in your dorm building, all 30 said that
a they got the flu vaccine. Does the result of your study make you doubt the 46% reported by the National Foundation for Infectious
