In academics, faculty typically start as assistant professors, are promoted to associate professor (and gain tenure), and finally reach the rank of full professor. Some have argued that women have a harder time gaining promotion to associate and full professor than do men. Do the data from this sample support that argument? The excel file labeled "Rank vs Sex" is the result of doing a google search to research this question. The data represents the faculty including the rank of instructor for Texas Tech University in the fall of 2013. The rank of instructor is lower than assistant professor. The data excludes those who are not ranked.

a. Using the data provided make a side by side bar chart to support see if the claim can be supported. (Hint: the colors will be based on female and male.)

b. In order to see if we have statistical evidence to support the claim perform a Chi-square test with sex as the rows and rank as the columns. Written analysis, give your answers and explain in the conclusions.
