Consider the Poisson trip generation model in Example 8.4. Suppose that a household has five members with an annual income of $150,000 and lies in a neighborhood with a retail employment of 320. What is the expected number of peak-hour shopping trips, and what is the probability that the household will make more than one peak-hour shopping trip.

Process: (1) Calculate the Poisson parameter (2) Determine the probability of making zero trips and one trip; (3) subtract the values from #2 from 1 to determine probability
