According to a Yale program on climate change communication survey, 71% of Americans think global warming is happening.† (a) For a sample of 16 Americans, what is the probability that at least 13 believe global warming is occurring? Use the binomial distribution probability function discussed in Section 5.5 to answer this question. (Round your answer to four decimal places.) (b) For a sample of 160 Americans, what is the probability that at least 110 believe global warming is occurring? Use the normal approximation of the binomial distribution to answer this question. (Round your answer to four decimal places.) (c) As the number of trials in a binomial di
