b. Identify the observational units.
c. Identify the explanatory and response variables. Also, for each variable, identify whether it is categorical or quantitative.
d. State the appropriate null and alternative hypotheses in words.
e. Explain why it would NOT be okay to use the theory-based method to find a p-value for this study.
f. Describe how one might use everyday items (for example, coins, dice, cards, etc.) to conduct a tactile simulation-based test of the hypotheses. Be sure to clearly describe how the p-value will be computed from the simulation.
g. Use an appropriate applet (for example, the Multiple Proportions applet) to find and report the following from the data: (i) the name of a statistic and its numeric value and (ii) the simulation based p-value.
h. Interpret the p-value in the context of the study.
i. State a complete conclusion about this study, including significance, causation, and generalization. Be sure to explain how you are arriving at your conclusion.
