In class, we compared healing times for females who received an experimental cold sore medicine. The data for the male control and treatment groups are provided below; they represent the number of days that passed before the sores were completely gone. In your notebook, make a dotplot for each group. Control: 20,13,22,21,16,5,21,11,16,14,15,15,13,16,10,17,16,11,21 Treatment: 11,16,8,16,15,12,11,12,12,9,11,19,16,13,5,15,12,8,11 Part A: Calculate the mean healing time for the control group, rounding your result to the nearest hundredth. In your notebook, mark an "X" on the horizontal axis of your dotplot to show the mean.Mean =  daysPart B: Calculate the mean healing time for the treatment group, rounding your result to the nearest hundredth. In your notebook, mark an "X" on the horizontal axis of your dotplot to show the mean.Mean =  days
