Suppose the amount of cereal in a package cannot be weighed exactly. In fact, it is a normally distributed random variable, with # = 10.10 oz. add o = .040 oz. On the package is claimed, "net weight, 10 oz."
(a) What proportion of the packages are underweight?
(b) to what value must the mean # be raised in order that only 1/10 of 1 % of the packages be underweight?
