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, 25 occurred on a Monday, 17 occurred on a Tuesday, 16 occurred on a Wednesday, 12 occurred on a Thursday, and 30 occurred on a Friday
