Please do not give solution in image format thanku According to a study done by Nick Wilson of Otago University Wellington, the probability a randomly selected individual will not cover his or her mouth when sneezing is 0.267. Suppose you sit on a bench in a mall and observe people's habits as they sneeze. Complete parts (a) through (c). (a) What is the probability that among 18 randomly observed individuals, exactly 8 do not cover their mouth when sneezing? - Using the binomial distribution, the probability is : (Round to four decimal places as needed.) (b) What is the probability that among 18 randomly observed individuals, fewer than 4 do not cover their mouth when sneezing? - Using the binomial distribution, the probability is : (Round to four decimal places as needed.) (c) Would you be surprised if, after observing 18 individuals, fewer than half covered their mouth when sneezing? Why? - (Yes/no) it (would/would not) be surprising, because using the binomial distribution, the probability is: ____ which is (less/greater) than 0.05. (Round to four decimal places as needed.)
