For the 55-year period since 1960, there were 336 Atlantic hurricanes. Assuming the Poisson distribution, a) find µ, the mean number of hurricanes per year; b) find the probability that in a randomly selected year, there are exactly 8 hurricanes; c) in this 55-year period, there were actually 5 years with 8 Atlantic hurricanes. How does this actual result compare to the probability found in part (b)? Does the Poisson distribution appear to be a good model in this case?
