In a recent poll, 45% of survey respondents said that, if they only had one child, they would prefer the child to be a boy. Suppose you conducted a survey of 160 randomly selected students on your campus and find that 84 of them would prefer a boy. Complete parts (a) and (b) below Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). (a) Use the normal approximation to the binomial to approximate the probability that, in a random sample of 160 students, at least 84 would prefer a boy, assuming the true percentage is 45% The probability that at least 84 students would prefer a boy is 0 (Round to four decimal places as needed.) (b) Does this result contradict the pol? Explain. OA. No, because the probability from part (a) is less than 0.05 Therefore, the survey results are not unusual OB Yes, because the probability from part (a) is less than 0.05. Therefore, the survey results are unusual OC. Yes, because the probability from part (a) is greater than 0.05. Therefore, the survey results are unusual OD. No, because the probability from part (a) is greater than 0.05 Therefore, the survey results are not unusual
