In a city, 70% of the people prefer Candidate A. Suppose 30 people from this city were sampled. Use the normal approximation to the binomial distribution to estimate: What is the probability that 80% or more of this sample will prefer Candidate A? What is the probability that 45% or more of this sample will prefer some other candidate?
