tutor3 : Hello Student, May I help you with your Math problems?
student : i hope so!
student : i have this data set, and along with it, there is the following question:
student : a) Does the data suggest that the overall frequency of hurricanes has changed over time in the U.S. or have they been constant over the last 13 decades? State your hypotheses, test statistic, p-value, and conclusion. Also confirm that all assumptions/conditions for your test are met. If frequencies have changed, explain how they have changed and in which decades. If not, explain why there were only 12 observed hurricanes in the 70s but double that number in the 40s.
student : there are 3 columns of data, sorted into low, medium, and high intensities
student : i'm just not sure what type of test to use. is it the goodness of fit test?
student : ?
tutor3 : Please wait, we are helping other students
