Based on this information, reports that the incidence of breast
cancer is higher in Alabama than in Alaska. Can we say with
certainty that this headline is accurate? Why or Why not

Alaska. This means that it would change the denominator of the
incidence rate so it is not a known fact that one would have a
higher incidence rate based on the information provided.
