(a) What is the probability that among 16 randomly observed individuals exactly 5 do not cover their mouth when sneezing? (b) What is the probability that among 16 randomly observed individuals fewer than 4 do not cover their mouth when sneezing? (c) Would you be surprised if, after observing 16 individuals, fewer than half covered their mouth when sneezing? Why? (a) The probability that exactly 5individuals do not cover their mouth is nothing. (Round to four decimal places as needed.) (b) The probability that fewer than 4 individuals do not cover their mouth is nothing. (Round to four decimal places as needed.)arrow_forwardA has an inspection system for the batches of chicken purchased from a supplier. A company batch typically contains 200 chicken. In a quality control system, a random sample of 10 chicken from each batch are selected and tested.
