Question

The data in the Tollowing table are the frequency counts for 40o observations on the number of bacterial colonies within the field of a microscope, using samples of milk film. Is there sufficient evidence to claim that the data do not fit the Poisson distribution? (Use a-0.05.) State the null and alternative hypotheses. O My The data fit a Poisson distribution. The data do not fit a Poisson dstribution. O Mo The data do not fit a Poisson distribution. The data fit a Poisson distribution. Calculate the test statistic. (Combine cells 7 through 19 as a single group for Number of Colonies per Field and sum the Frequency of Observation values. Round your answer to three decimal places.) Find the p-value associated with the test in statistic. p-value < 0.005 0.005< p-value<0.010 0 0.010 p-value < 0.025 O 0.025 p-value < 0.050 0.050 p-value <0.100 Op-value>0.100 What is the conclusion of your test? Reject M There is not sufficient evidence to conclude that the observations do not follow a Poisson distribution. O Reject Me There is sufficient evidence to conclude that the observations do not follow a Poisson distribution. O Fail to reject There is sufficient evidence to conclude that the observations do not follow a Poisson distribution. O Fail to reject There is not sufficient evidence to conclude that the observations do not follow a Poisson distribution. You may need to use the appropriate appendix table or technology to answer this question.
