Reconsider the previous two exercises. Students at Cal Poly collected data from their classmates and produced the following two-way table of counts:

a. Produce a segmented bar graph to display these data. Comment on what the graph reveals.

b. Perform a simulation-based analysis using the chi-square statistic. Submit a screen capture of the simulated null distribution and report the approximate p-value.

c. Based on the approximate p-value from the simulation analysis, would you conclude (at the 0.05 significance level) that there is an association between sex and coffee consumption?

d. Summarize your conclusions from this analysis.

Data from previous exercise

Reconsider the previous exercise about sex and coffee consumption. The sample data could be organized in a two-way table as follows:
