Question

In a New York Times/CBS News poll, respondents were asked if it should be legal or illegal to use hand-held cell phones while driving. One hundred forty-one said that it should be legal, and 663 said that it should be illegal. What is the probability of randomly selecting someone who believes it should be legal to use a hand-held cell phone while driving? Is it unlikely to randomly select someone with that belief?
Consider an event to be “unlikely” if its probability is less than or equal to 0.05. (This is equivalent to the same criterion commonly used in inferential statistics, but the value of 0.05 is not absolutely rigid, and other values such as 0.01 are sometimes used instead.)
