A medical journal published the results of a study to compare the effectiveness of handwashing with soap and handrubbing with alcohol. Health care workers who used handrubbing had a mean bacterial count of 32 per hand with a standard deviation of 60. Health care workers who used handwashing had a mean bacterial count of 63 per hand with a standard deviation of 105. In a random sample of 50 health care workers, all using the same method of cleaning their hands, the mean bacterial count per hand, x, is greater than 65. Give your opinion on whether this sample of workers used handrubbing with alcohol or dweebing with
