A recent study of a
random sample of employees evaluated whether satisfaction is
related to job performance. 250 employees who have been employed
greater than 10 years, and 250 employees who have been employed
less than 10 years were included in the study. The number of
employees who still worked for the company after this study were
236 and 226, respectively. Assume that the two groups are
independent, and that satisfaction rates follow a normal
distribution in the population. Use...
