Conducting a hypothesis test is accomplished when a business researcher wants to examine the difference in the mean values of two samples or populations. An example would be when one would like to test two different brands of batteries to determine which one last longer than the other. This type of testing will allow one to determine if the means are different (Black, 2004).
