A study of 240 randomly selected residents of a subtropical resort city with 82,000 residents found that 5.4% of them had been exposed to the mosquito-borne virus that causes Dengue fever. Suppose the actual percentage of people in the city who have been exposed to the virus is 3%. Let = the proportion of residents who have been exposed in a random sample of 240. If the true proportion is actually 0.03, the probability that is more than 0.054 is closest to a. 0 b. 0.0222 c. 0.0207 d. 0.0146 e. We can’t calculate this probability because we have not satisfied the Normality condition.
