Question: Managers of a major book publisher believe that the occurrence of typographical errors in the books the company publishes is Poisson distributed with a mean of 0.2 per page. Because of some customer quality complaints, the managers have arranged for a test to be conducted to determine if the error distribution still holds. A total of 400 pages were randomly selected and the number of errors per page was counted. These data are summarized in the following frequency distribution:

Errors              Frequency

   0                     335

   1                      56

   2                       7

   3                       2

Total                  400

Conduct the appropriate hypothesis test using a significance level equal to 0.01. Discuss the results.
