A recent report suggests that Chief Information Officers (CIO's) who report directly to Chief Financial Officers (CFO's) rather than Chief Executive Officers (CEO's) are more likely to have IT agendas that deal with cost cutting and compliance. In a random sample of 826 companies, it was found that CIO's reported directly to CFO's in 159 out of 504 service firms and in 103 out of 322 manufacturing companies. Complete parts a through c below. a) Is there evidence that type of business (service versus manufacturing) and whether or not the CIO reports directly to the CFO are associated? State the null and alternative hypotheses. Choose the correct answer below. A. Ho: The proportions of CIO's reporting to a CFO are the same. HA: The proportions of CIO's reporting to a CFO are different. B. Ho: The proportions of CEO's reporting to a CFO are the same. HA: The proportions of CEO's reporting to a CFO are different. O C. Ho: The proportions of CIO's reporting to a CFO are different. HA: The proportions of CIO's reporting to a CFO are the same. O D. Ho: The proportions of CEO's reporting to a CFO are different. HA: The proportions of CEO's reporting to a CFO are the same. Determine the y statistic. x2 = (Round to two decimal places as needed.)
