Suppose that Air France would like to determine if the number of lost bags per flight follows the Poisson probability distribution with a mean of 0.7 bags. To test this hypothesis, the following data were collected from 200 randomly selected flights:

Number of Lost Bags per Flight Frequency 0 106 1 63 2 22 3 4 4 3 5 or more 2

a. Using a = 0.05, determine if the number of lost bags per Air France flight follows the Poisson probability distribution when l = 0.7.

b. Determine the p-value using Excel and interpret its meaning.
