Goodness of Fit

A personnel director believes that the distribution of the reasons workers leave their jobs is different from percentages that were given in a USA Today article. The article stated 41% leave their job due to limited advancement potential, 25% for lack of recognition, 15% for low salary and benefits, 10% are unhappy with management, and 9% are bored and/or do not have a reason. The director randomly selects 200 workers who recently left their jobs and asks each his or her reason for doing so. The results are shown below. Using the guidelines on page 512 in our textbook (goodness of fit test), test the claim that the distribution is different. Use a = 0.01.
