The CEO of a medical supply company is committed to expanding the proportion of highly qualified women in the organization’s large staff of salespersons. Given the recent hiring practices of his human resources director, he claims that the company has increased the proportion of women in sales positions throughout the organization between 2005 and 2010. Hoping to find support for his claim, he directs his assistant to collect random samples of the salespersons employed by the company in 2005 and 2010. These data are listed in the file P09_13.xlsx. Test the CEO’s claim using the sample data and report a p-value. Is there statistical support for the claim that his strategy is effective?
