Chi-square (Discrete Distribution)
The data appears to be Poisson distributed. Thus the parameter estimator, . To test the goodness-of-fit, the following hypotheses are formed:
H0: the random variable is Poisson distribution
H1: the random variable is not Poisson distribution
The pmf is given by:
for , the probabilities for various value of x are:
P(0) = 0.026 P(6) = 0.085
P(1) = 0.096 P(7) = 0.044
P(5) = 0.140 P(11) = 0.001
