• 20 of the 27 minority coaches are first base coaches
• 10 of the 33 nonminority coaches are first base coaches
a. Is this an observational study or an experiment?
b. Identify the explanatory and response variables.
c. Organize these counts in a 2 × 2 table, with the explanatory variable in columns.
d. Conduct a simulation analysis and report the p-value.
e. Summarize your conclusion about whether the data provide strong evidence that minority coaches are more likely to be first base coaches than nonminorities.
f. Is drawing a cause-and-effect conclusion warranted in this study? Explain.
