Problem 23. The number of phone calls received by a ticket agency on any one day is Poisson distributed. On an ordinary day, the expected value of the number of calls is do, and on a day where there is a popular show in town, the expected value of the number of calls is An, with An > Ap. Describe the LRT for deciding whether there is a popular show in town based on the number of calls received. Assume a given probability of false rejection, and find an expression for the critical value
