Using the five steps of hypothesis testing, explain what the researcher might have done, including the appropriate analysis, and interpret the results. This part of the assignment includes many parts. First, as a group you must decide which statistical test has been completed below for you. (Most likely this will be a t-test or an ANOVA.) Then you will develop the null and alternative hypotheses based on the test you decided upon. Finally, since the test has already been competed below, it will be your responsibility to explain these results. Are there any problems with this study? If so, explain what they are.
