2. As an alternative to hand washing, some hospitals allow health workers to rub their hands with an alcohol-based antiseptic. The British Medical Journal (Aug 17, 2002) reported on a study to compate the effectiveness of washing the hands with soap and rubbing the hands with alcohol. One group of health care workers used hand rubbing, while a second group used hand washing to clean their hands. The bacterial count (number of colony-forming units) on the hand of each worker was recorded. The table gives descriptive statistics on bacteria counts for the two groups of health care workers. Hand rubbing ī = 35 Hand washing = 69 a) Compute the coefficient of variation for each hand-cleaning method. s = 59 s = 106 b) Compute a 75% Chebyshev interval around the mean for each hand-cleaning method. c) On the basis of your results in part b), make an inference about the effectiveness of the two hand-cleaning methods.
