Combining random variables
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 0 = 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 4 dots of frosting on a randomly chosen cookie.
Find the standard deviation of T.
Choose 1
OT = 0.25 grams
B
OT = 0.5 grams
OT = 0.75 grams
OT 1 gram
