A large bakery uses a machine to dispense frosting onto its cookies. A certain type of cookie gets 4 dots of frosting on top of each cookie. The dots of frosting have a mean mass of u = 3 grams and a standard
deviation of o = 0.25 grams. We can assume that the masses of the dots of frosting are independent from
each other. Let T be the total mass of the dots of frosting on a randomly chosen cookie.
Find the mean of T.
HT =
grams
