Question: A random sample of 50 cans of peach halves has a mean weight of 16.1 ounces and a standard deviation of .4 ounce. If x-bar= 16.1 ounces is used as an estimate of the average weight of all the cans of peach halves in the large lot from which the sample came, with what confidence can we assert that the error of this estimate is at most .1 ounce?
