Your answer is partially correct. Please use the accompanying Excel data set or accompanying Text file data set when completing the following exercise. Consider the following frequency table of observations on the random variable X. Values 0 1 2 3 4 Obs. Val. 24 30 31 11 4 Based on these 100 observations, is a Poisson distribution with a mean 1.2 an appropriate model? Perform a goodness-of-fit procedure with a = 0.05. (a) Calculate the test statistic y . Round your answer to two decimal places (e.g. 98.76). 7.01 (b) Is the Poisson distribution with a mean of 1.2 an appropriate model? Yes
