TABLE 5-9 A Major Hotel Chain Keeps a Record of the Number

question 140

Short Answer

TABLE 5-9
A major hotel chain keeps a record of the number of mishandled bags per 1,000 customers. In a recent year, the hotel chain had 4.06 mishandled bags per 1,000 customers. Assume that the number of mishandled bags has a Poisson distribution.
-Referring to Table 5-9, what is the probability that in the next 1,000 customers, the hotel chain will have more than five but less than eight mishandled bags?
