Question

About 34% of people are expected to be infected by the flu this season. What is the risk that a randomly selected person will be infected by the flu?'a) 34 b) 0.34 c) 0.66 d) 66 e) 1 divided by the population size

Answer 1

B 0.34

Explanation:

If 34% of all people are expected to get the flu, then that means 34% of any sample size should also expect to be infected. If they choose 1 person at random from either the population or a preselected random sample, then that person has a 34% chance of getting the flu. 0.34 is the decimal corresponding to 34%. So the probability is 0.34
