Let X be the lengths of a particular animal's pregnancies
X is N(252, 20)
(a) What proportion of pregnancies lasts more than 262 days?

(b) What proportion of pregnancies lasts between 227 and 257 days?

(c) What is the probability that a randomly selected pregnancy lasts no more than 237 days?
P(X<237) = 0.2266
(d) A "very preterm" baby is one whose gestation period is less than 202 days. Are very preterm babies unusual?
