Freedom Hospital is in the midst of contract 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. The doctors’ negotiator recently mentioned the geriatric charge system does not make sense. The negotiator is concerned there is a greater variability in the total charges for men than in the total charges for women. To investigate this issue, the hospital collected a random sample of data for 138 patients. The 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.
