Identify an example in which a comparative standard or claim is made about two independent populations.

For example, Car Type A gets more average miles per gallon in urban driving than Car Type B. The standard or claim may be expressed as a mean (average), variance, standard deviation, or proportion. Collect two appropriate random samples of data and perform a hypothesis test. Report on your results. Be sure to include in your report the comparison expressed as a hypothesis test, a description of the data collected, the analysis performed, and the conclusion reached.
