A random sample of 60 cans of peach halves has a mean weight of 16.1 ounces and a standard deviation of 0.3 ounces. If x = 16.1 ounces is used as an estimate of the mean weight of all cans of peach halves in the large lot from which the sample came, with what confidence can we say that the error in that estimate is at most 0.1 ounce?
