An engineer believes thаt the number оf defects оn а prоduct he is working on hаs the Poisson pmf. He collects a sample of 25 and notes the number of defects on each product. The sorted data are 0, 0, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4. Perform a Chi-Square Goodness of Fit test on these data. Take all intermediate computations to four decimal places. How many degrees of freedom will the test statistic have?
