A tourist agency wants to know what proportion of visitors to a popular landmark are from a specific foreign country. To find out, they survey 50 people in the line to purchase tickets to see the landmark on a Sunday afternoon in May. Are all the assumptions and conditions for finding the sampling distribution of the proportion satisfied? Explain briefly. Choose the correct answer below. A. Yes, as long as there were more than 500 people in line that day, the sample size is sufficient. B. Yes, as long as the day they picked to perform the survey was chosen at random, the observations will be independent. C. No, it is likely that families have gone to see the landmark together, so the observations will not be independent. D. No, due to the popularity of the landmark, the sample size is not large enough.
