Use a significance level of 0.01 to test the claim that workplace accidents are distributed Monday through Friday 25%, 15%, 15%, 15%, and 30% respectively. A study of 100 workplace accidents showed 24, 15, 16, 13, and 32 occurred on Monday through Friday respectively.
|
| Because the critical value is  and the test statistic is 0.507, accept that workplace accidents occur Monday through Friday with the respective percentages 25%, 15%, 15%, 15%, and 30%. |
| Because the critical value is  and the test statistic is 13.277, accept that woorkplace accidents occur Monday through Friday with the respective percentages 25%, 15%, 15%, 15%, and 30%. |
| Because the critical value is  and the test statistic is 0.507, reject that workplace accidents occur Monday through Friday with the respective percentages 25%, 15%, 15%, 15%, and 30%. |
