Question a recent study reported that 2525% of the residents of a particular community lived in poverty. suppose a random sample of 200200 residents of this community is taken. we wish to determine the probability that 2929% or more of our sample will be living in poverty. complete parts (a) and (b) below. before doing any calculations, determine whether this probability is greater than 50% or less than 50%. why? the answer should be less than 50%, because the resulting z-score will be negative and the sampling distribution is approximately normal. the answer should be greater than 50%, because 0.24 is greater than the population proportion of 0.20 and because the sampling distribution is approximately normal. the answer should be less than 50%, because 0.24 is greater than the population proportion of 0.20 and because the sampling distribution is approximately normal. the answer should be greater than 50%, because the resulting z-score will be positive and the sampling distribution is approximately normal. calculate the probability that 24% or more of the sample will be living in poverty. assume the sample is collected in such a way that the conditions for using the clt are met. p (p ge 0.24) = (round to three decimal places as needed.)
