You recommend that the school district experiment with a computer mediated approach and compare with the textbook approach. The results of your research are posted below. Once the results were in, the school wants to know if there is a reliable difference in achievement levels between the computerized and standard textbook groups or is this just a fluke (one time or rare event). Briefly describe the appropriate statistical strategy and mathematical expressions (conceptual terminology) for addressing this problem. Be sure to explain the rationale behind your choice of strategy. Be sure and show how you will explain to the school district the role of chance that has to be factored in the decision.
