10 }} A rare condition called RCX affects very few people - perhaps on the order of one in a thousand. The center for rare diseases wishes to form a more accurate estimate of the actual probability of RCX occurrence. To do so, n people are selected at random and the number of those who have RCX is noted. The probability of a person being affected by RCX is then estimated as the usual ratio of the number of affected to the total number of people chosen for the study. The center for rare diseases must guarantee that their estimate has 95% confidence around 0.5 of the true value, meaning that P{|P - P| 95%, where e = 0.5, P is the true probability of RCX occurrence and P is its estimate based on a random sample of n people. Which of the following choices satisfy the requirement: None of the offered choices satisfy the requirement. On = 10, 000 On = 40, 000 On = 100, 000
