Cases of UFO sightings are randomly selected and categorized according to month, with the results listed in the table below (based on data from Larry Hatch). Use a 0.05 significance level to test the claim that UFO sightings occur in the different months with equal frequency. Is there any reasonable explanation for the two months that have the highest frequencies?

Conduct the hypothesis test and provide the test statistic, critical value and or P-value, and state the conclusion.
