A conservative candidate captured 48 percent of the popular vote in her riding in the last federal election. In a sample of 50 people from the candidate's riding, 35 claim to have voted for the conservative candidate. What is the probability in a sample of this size that 35 or more persons would have voted for this candidate? that 13 or fewer persons would have voted for this candidate? That either one or the other of these alternatives would have occurred? Then is there any reason to suspect that this sample may not be representative of the total population in the riding, or that some of the individuals in the sample are not being truthful about the way they voted?
