A study compares the effectiveness of washing the hands with soap and rubbing the hands with alcohol in hospitals. 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 below shows the descriptive statistics on the bacteria counts for the two groups. Complete parts a through c below. Hand rubbing Hand washing Mean 31 71 Standard Deviation 58 93 Cun
