What value of x would have a z-score of 1.56?The number of times that a person has a cold each year is a Poisson random variable with parameter λ = 5. Suppose that a new drug has been developed that reduces this to λ = 3, but that the drug only works for 75% of the population. For the remaining 25% of the population there is no effect. A person takes the drug for an entire year. During the year the person had 2 colds. What is the probability that the drug had an effect on this person?
