A poll showed that 55% of randomly surveyed adults in a certain country said their country benefits from having a rich class. Complete parts (a) through (h) below. a. Assuming the sample size was 500, how many would have said that their country benefits from having a rich class? Assuming the sample size was 500, 275275 people in the sample would have said that their country benefits from having a rich class. (Round to the nearest integer as needed.) b. Is the sample size large enough to apply the Central Limit Theorem? Explain. Assume the other conditions for using the CLT are met. Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to the nearest integer as needed.) A. Yes, the sample size is large enough, since the estimated standard error is nothing, which is greater than or equal to 10. B. No, the sample size is not large enough, since the estimated standard error is nothing, which is less than 10.…
