The CEO of a medical supply company is committed to expanding the proportion of highly qualified women in the organization’s staff of salespersons. He claims that the proportion of women in similar sales positions across the country in 2010 is less than 50%. Hoping to find support for his claim, he directs his assistant to collect a random sample of salespersons employed by his company, which is thought to be representative of sales staffs of competing organizations in the industry. These data are listed in the Data 2010 sheet of the file P09_13.xlsx. Test this manager’s claim using the given sample data and report a p-value. Is there statistical support for his hypothesis that the proportion of women in similar sales positions across the country is less than 50%?
