The Central Limit Theorem for Sums (Optional) · Exercise 33

Suppose that the weight of open boxes of cereal in a home with children is uniformly distributed from two to six pounds with a mean of four pounds and standard deviation of 1.1547. We randomly survey 64 homes with children.

(a) In words, X = _____________.
(b) The distribution is _______.
(c) In words, ΣX = _______________.
(d) ΣX ~ _____(_____, _____)
(e) Find the probability that the total weight of the open boxes is less than 250 pounds.
(f) Find the 35^th percentile for the total weight of open boxes of cereal.
