Buff n' Tuff Products produces bottles of free-range steroids. The stated size of each bottle is 20 ounces. In order to assess the accuracy of the bottle-filling process, Buff n Tuff took 10 samples of 6 observations each when the process was working as expected. The table below shows the weight (in ounces) for each sample bottle. Buff n' Tuff Products produces bottles of free-range steroids. The stated size of each bottle is 20 ounces.
