Hurricanes in a particular place arrive with a mean of 3.25 per year. Suppose the number of hurricanes can be modeled by a Poisson distribution with this mean.

a) What's the probability of no hurricanes next year?

b) What's the probability that during the next two years, there's exactly 1 hurricane?

    It is proposed to model the onset of hurricanes anywhere in the Gulf of Mexico as a Poisson process. The rate of occurrence, however, depends strongly on the month of the year. Specifically, we assume that hurricanes occur in only three months of the year: August, September, and October. During these months, the mean hurricane occurrence rate per month is as follows: Month Mean occurrence rate August 1.0 event per month September 2.0 events per month October 1.0 event per...

    Suppose during the next three decades, the average number of hurricanes per decade is as follows: 4, 6, and 8. Drawing on the statistical reasoning concepts in Huff and your weekly readings, compare and contrast these three decades to the previous 16 decades of hurricane data in Part 1. Answer the following questions. What are the 3 potential hypotheses when comparing these data to the previous 16 decades of hurricane data in Part 1. Which hypothesis can you accept? Why?...

    The circled answer is wrong please show steps to arrive at a correct answer. Company ABg offers hurricane insurance to homeowners in Texas. Assume that the premium collected for hurricane insurance can be modeled by an Ex- ponential distribution with a mean of 3. Suppose that the hurricane losses can be modeled by an Exponential distribution with a mean of 1. If the premium collected and hurricane losses are independent, what is the probability that the ratio of losses to...
