Telecommuting As an alternative to flextime, many companies allow employees to do some of their work at home. Individuals in a random sample of 300 workers were classified according to salary and number of workdays per week spent at home.
| Â | Workdays at Home per Week | ||
| Â | Less Than One | At Least One, but Not All | All at Home |
Salary | |||
Under $25,000 | 38 | 16 | 14 |
$25,000 to $49,999 | 54 | 26 | 12 |
$50,000 to $74,999 | 35 | 22 | 9 |
Above $75,000 | 33 | 29 | 12 |
a. Do the data present sufficient evidence to indicate that salary is dependent on the number of workdays spent at home? Test using a = .05.
b. Use Table 5 in Appendix I to approximate the p-value for this test of hypothesis. Does the p-value confirm your conclusions from part a?
