Don Carpita owns and operates Carpita Bottling Company in Lakeland, Wisconsin. The company bottles soda and beer and distributes the products in the counties surrounding Lakeland.The company has four bottling machines, which can be adjusted to fill bottles at any mean fill level between 2 ounces and 72 ounces. The machines exhibit some variation in actual fill from the mean setting. For instance, if the mean setting is 16 ounces, the actual fill may be slightly more or less than that amount.Three of the four filling machines are relatively new, and their fill variation is not as great as that of the older machine. Don has observed that the standard deviation in fill for the three new machines is about 1% of the mean fill level when the mean fill is set at 16 ounces or less, and it is 0.5% of the mean at settings exceeding 16 ounces. The older machine has a standard deviation of about 1.5% of the mean setting regardless of the mean fill set-ting. However, the older machine tends to…
