Did you wash your hands with soap before eating? You\'ve undoubtedly been asked that question a few times in your life. Mom knows that washing with soap eliminates most of the germs you\'ve managed to collect on your hands. Or does it? A student decided to investigate just how effective washing with soap is in eliminating bacteria. To do this she tested four different methods-washing with water only, washing with regular soap, washing with antibacterial soap (ABS). and spraying hands with antibacterial spray (AS) (containing 65% ethanol as an active ingredient). Her experiment consisted of one experimental factor, the washing Method, at four levels. She suspected that the number of bacteria on her hands before washing might vary considerably from day to day. To help even out the effects of those changes, she generated random number* to determine the order of the four treatments. Each morning she washed her hands according to the treatment randomly chosen. Then she placed her right hand on a sterile media plate designed to encourage bacteria growth. She incubated each plate for 2 days at 36degree C. after which she counted the bacteria colonics. She replicated this procedure 8 times for each of the four treatments. Below is the data. Enter the data in a Minitab Worksheet -save the file as bacteria.mtw. Perform a 4C\'s analysis to determine if a difference exists in the number of bacteria colonies among the four different treatments. Perform a Bonferroni and Tukey multiple comparison procedure to identify which pairs of treatment are significantly different. Do these procedures give the same results? Use Dunnet\'s procedure with Soap as the control group, to compare the other three methods to regular soap and water handwashing. Give the conclusions of that procedure.
