Twenty-four hours later, you look at the plates and measure the zone of inhibition of bacterial growth. The bigger the zone of no growth, the more effective the antibiotic. You take the following measurements (mm) Xepotan 4.28 3.81 4.08 3-28 3.88 4.09 3.97 2.46 3.71 4-17 Water O O 1.04 4.98 0 O 1.00 O O To compare the zone of inhibition of bacterial growth in the two groups, we calculate the sample means. What is the mean of the zone of no growth in plates with a disk of Xepotan? What is the mean of the zone of no growth in plates with a disk of water
