At a recent shareholders' meeting, the CEO of one of the nation's largest retailers claimed an employee satisfaction rate of 50%. To test the validity of this claim, the Senior Vice President (SVP) for Research conducted a survey of the company's employees. The SVP for Research defined her null hypothesis, Ho: p 0.50, and formulated her alternative hypothesis, H₁: p < 0.50, to = indicate her belief that the job satisfaction rate would be lower than 50%. In the null and alternative hypotheses, p denotes the proportion of employees who are satisfied with their jobs. A random sample of 4000 employees revealed that 1960, or 49%, agreed with the statement, "I am satisfied with my job." The following computer output corresponds to the analysis of the employee data.
