A produce packing company prepares crates of apples to ship to supermarkets. Suppose
that the weight of a randomly selected crate is known to be Normally distributed, with
a mean of 14 kg and a standard deviation of 1.4 kg.
(a) Find the weight of a particular crate such that the probability of randomly selecting a heavier crate is 0.05.
(b) Find the probability that a randomly selected crate will weigh more than 16kg.
(c) If 20 crates are randomly and independently selected, what is the probability that
at least 2 of them will weigh more than 16kg?
