Is there a changes in TV 'on' time between these cities?

An independent investigator has decided to study variations in TV viewing habits among three American cities. She has managed to arbitrarily sample households in Chicago, Atlanta, and Minneapolis and gather data on the daily "on" times for households on a typical day. The data is specified below. Can we approximately with statistical certainty there are differences in TV 'on' time between these cities?
