Be sure to include the following in your paper:Formulate a set of verbal hypothesis statements (null and alternate hypothesis). Describe and perform the five-step hypothesis test process: set up the hypothesis, select a level of significance, establish the decision rule, calculate the test statistic, and draw conclusion. Describe the results of your test, and explain how the findings from this hypothesis testing can be used to answer the research question above. Be sure to include, in an appendix, your raw data table and results of your computations of a z-test or t-test in your paper.
