Question: The U.S. prison population grew exponentially between 1980 and 2000. A researcher is interested in testing to see whether that increase reflected increases in crime or whether it was the result of a conservative shift that occurred during this same time. Crime data was collected for the decades of the 70s, 80s and 90s. The researcher wants to test the hypothesis that there was no difference in the number of UCR Part 1 crimes during those 3 decades.
