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 ham bacterial count of 36 per hand with a standard deviation of 57. Health care workers who used handwashing had a mean bacterial count of 70 per hand with a standard deviation of 104. sample of 50 health care workers, all using the same method of cleaning their hands, the mean bacterial count per hand, x, is less than 35. Give your opinion on whether this sample of handrubbing with alcohol or handwashing with soap. Click the icon to view the table of normal curve areas. Since the probability of x being less than 35 is is more likely that this sample of workers used Ca if this sample of workers used handrubbing with alcohol, and if they used handwashing
