Refer to Exercise 5.4.12. Find the probability that 85% or more of the sampled mussels will be infected, using the normal approximation with the continuity correction.
Exercise 5.4.12
In a certain population of mussels (Mytilus edu-lis), 80% of the individuals are infected with an intestinal parasite.1 A marine biologist plans to examine 100 randomly chosen mussels from the population. Find the probability that 85% or more of the sampled mussels will be infected, using the normal approximation without the continuity correction.
