statistics

A random sample X 2 (X1, X2: . . . , X\"), (n = 50) is obtained observing the number of monthly counts of inuenza cases occuring across medical clinics in a city. The baseline montly count is 60 = 7 Whilst the maximum likelihood estimate 3 = 9 is obtained from the sample X. Propose a suitable statistical model for this dataset and evaluate using a likelihood ratio test to determine Whether or not there is statistical evidence of a change in the montly mean number of inuenza cases in the city. Note at o: = 0.01, xl a) = 6.635
