Consider testing a hypothesis that the yearly number of earthquakes felt on a certain island has mean lambda not greater that 2. In the past two years, 3 and 5 earthquakes were recorded. Assuming that the total number of earthquakes in a two year period is Poisson distributed with mean (2 times lambda), find the p-value of the data. The answer is 0.051. Please can anyone explain ?
