One strategy that may have an impact on employee retention, turnover and engagement is a successful employee recognition program. Surveying small organizations, those with 500 to 2,499 employees, and large organizations, those with 10,000 or more employees, a survey organization showed that 328 (76%) of the 430 small organizations have employee retention programs as compared to 169(87%) of the 195 large organizations. Complete parts (a) through (c) below. a. At the 0.05 level of significance, is there evidence of a significant difference between organizations with 500 to 2,499 employees and organizations with 10,000 or more employees with respect to the proportion that have employee recogniti programs? Let group 1 be the organizations with 500 to 2,499 employees, and let group 2 be the organizations with 10,000 or more employees. State the null and alternative hypotheses. Choose the correct answer below. 'A. Ho: R = 12 Hp : Ty #12 O c. Hoita 232 Hp : Is < 12 O E. Hoita si H: 11 12 O B. Ho: aq <h2 Hp : 7, ZI2 O D. Hoing #52 H:11 =12 O F. Ho : Tg >72 Hp : aq ST2 Calculate the test statistic. XŞTAT = 2.981 (Round to three decimal places as needed.)

Determine the critical value(s) for this test of hypothesis. Find the p-value in (a) and interpret its meaning. Construct and interpret a 95% confidence interval estimate for the difference between organizations with 500 to 2,499 employees and organizations with 10,000 or more employees with respect to the proportion that have employee recognition programs. The 95% confidence interval is
