Answer:

Step-by-step explanation:

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?

$P(X>262) = 0.3085$

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

$P(227$

(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?

$P(X$

Yes very unusual since probability is very near to 0.
