noise levels

11.  Noise Levels in Hospitals In the hospital study cited in

Exercise 19 in Exercise set 8–1, the standard deviation of the noise levels of the 11 intensive care units was

4.1 dBA, and the standard deviation of the noise levels of 24 nonmedical care areas, such as kitchens and machine rooms, was 13.2 dBA. At a = 0.10, is there a significant difference between the standard deviations of these two areas?

 12.  Heights of World Famous Cathedrals The heights (in feet) for a random sample of world famous

cathedrals are listed below. In addition, the heights for a sample of the tallest buildings in the world are listed. Is there sufficient evidence at a = 0.05 to conclude a difference in the variances in height between the two groups?
