Question: Freedom Hospital is in the midst of negotiations with its resident physicians. There has been a lot of discussion about the hospital’s ability to pay and the way patients are charged for services. The physicians’ negotiator recently mentioned that the geriatric charge system did not make sense. The negotiator is concerned that there is a greater variability in the total charges for males than in the total charges for females. To investigate this issue the hospital has randomly selected 138 patient files. These data are contained in the file Patients. Using the data for total charges, conduct the appropriate test to respond to the negotiator’s concern. Use a significance level of 0.05. State your conclusion in terms that address the issue raised by the negotiator.
