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 334 (77%) of the 431 small organizations have employee retention programs as compared to 174 (88%) of the 197 large organizations. Complete parts (a) through (c) below.

a.     At the 0.1 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 recognition programs? Determine the null and alternative hypotheses, where ty is the population proportion of organizations with 500 to 2,499 employees with employee recognition programs and t, is the population proportion of organizations with 10,000 or more employees with employee recognition programs.

Choose the correct answer below.

O A. Ho 11 = 12

H₂ : Ty Z T2

OB. Ho 11 = 12

H₂ : Ty > 2

O c. Ho ty z 22

H, Ty = 12

OD. Ho ty = 12

Hp : y = 12
