Question

The table below gives a frequency distribution describing the number of errors found in thirty 1,000-line samples of computer code. Suppose that we wish to determine whether the number of errors can be described by a Poisson distribution with mean μ = 4.5. Using the Poisson probability tables, fill in the table. Then perform an appropriate chi-square goodness-of-fit test at the .05 level of significance. What do you conclude about whether the number of errors can be described by a Poisson distribution with μ = 4.5? Explain.
