The results of Computerworld's Annual Job Satisfaction Survey showed that 28% of information systems (IS) managers are very satisfied with their job, 46% are somewhat satisfied, 12% are neither satisfied nor dissatisfied, 10% are somewhat dissatisfied, and 4% are very dissatisfied. Suppose that a sample of 500 computer programmers yielded the following results.
Category Number of Respondents
Very satisfied ..........105
Somewhat satisfied ........235
Neither ............ 55
Somewhat dissatisfied ...... 90
Very dissatisfied ......... 15
Use α = .05 and test to determine whether the job satisfaction for computer programmers is different from the job satisfaction for IS managers.
