population standard deviation of 16. From a sample of nine Atlanta area hospitals, they
found the portion of pneumonia patients who were given initial antibiotics within the
first four minutes of arrival had a standard deviation of 10. Use a .05 significance level
to test the claim that Atlanta area hospitals have less variation in the quality of care
given to pneumonia patients than United States hospitals.
