Consider a study testing whether birds were equally likely to rest on each streetlight. Researchers surveyed 30 randomly chosen streetlights in a city known to have many birds and counted the number of birds resting on each streetlight. Data on the number of birds seen on the lights are shown. (Note: No lights had more than three birds.) Using the ?2 value we obtained for a goodness-of-fit test comparing these data to the expectations from a Poisson process and the list of critical values shown, what is the conclusion of our test?
?
?
A) Fail to reject the null hypothesis, the birds appear randomly distributed on the streetlights
B) Fail to reject the null hypothesis, the birds appear non-randomly distributed on the streetlights
C) Reject the null hypothesis, the birds appear randomly distributed on the streetlights
D) Reject the null hypothesis, the birds appear non-randomly distributed on the streetlights
