Suppose in a population of 100,000, the probability that an individual will die from bird flu in a given winter is .00009. If the data fits a Poisson distribution, then the mean number of people in that population that will die from bird flu in one winter (rounded to the nearest whole number) is ?
If the same data fit a Poisson distribution, then the standard deviation of that population (rounded to the nearest whole number) is ?
