7. Nationwide, a certain disease occurs only a small proportion of people (.000215). A certain town has 74,000 residents. Use the Poisson approximation. What is the expected number of residents with the disease? (2 DECIMAL PLACES) (b) Determine the probability that the town has exactly 10 people with the disease. (4 NON-ZERO DECIMAL PLACES) (c) Determine the probability that the town has 30 or fewer residents with the illness. (4 NON-ZERO DECIMAL PLACES) (d) If the town had 31 or more residents with the disease, what would your thoughts be? (Use part c) (See answer choices on Top Hat.)
