Acandy maker produces mints that have a label weight of 20.4 grams. assume that the distribution of the weights of these mints is n(21.37,0.16). (a) let x denote the weight of a single mint selected at random from the production line. find p(x > 22.07). (b) suppose that 15 mints are selected independently and weighed. let y equal the number of these mints that weigh less than 20.857 grams. find p(y ≤2).
