1. Perform the indicated goodness-of-fit
test.
Use a significance level of 0.01 to test the claim that workplace
accidents are distributed on workdays as follows: Monday 25%,
Tuesday: 15%, Wednesday: 15%, Thursday: 15%, and Friday: 30%.
In a study of 100 workplace accidents, 26 occurred on a Monday, 15
occurred on a Tuesday, 17 occurred on a Wednesday, 17 occurred on a
Thursday, and 25 occurred on a Friday.

1. Use a significance level of 0.01 to test the claim that workplace accidents are distributed on workdays as follows: Monday 25%, Tuesday: 1596, Wednesday: 15%. Thursday: 15%, and Friday: 30%. In a study of 100 workplace accidents, 21 occurred on a Monday, 13 occurred on a Tuesday, 15 occurred on a Wednesday, 16 occurred on a Thursday, and 35 occurred on a Friday. Could these findings be a strong argument against the given claim on workplace accidents distribution?
