The lengths of a particular​ animal's pregnancies are approximately normally​ distributed, with mean muequals276 days and standard deviation sigmaequals16 days. ​(a) What proportion of pregnancies lasts more than 300 ​days? ​(b) What proportion of pregnancies lasts between 268 and 288 ​days? ​(c) What is the probability that a randomly selected pregnancy lasts no more than 248 ​days? ​(d) A​ "very preterm" baby is one whose gestation period is less than 240 days. Are very preterm babies​ unusual?

The proportion of pregnancies that last more than 300 days is nothing. ​(Round to four decimal places as​ needed.)

​(b) The proportion of pregnancies that last between 268 and 288 days is nothing. ​(Round to four decimal places as​ needed.)

​(c) The probability that a randomly selected pregnancy lasts no more than 248 days is nothing. ​(Round to four decimal places as​ needed.)

​(d) The probability of a​ "very preterm" baby is nothing. This event ▼ would be would not be unusual because the probability is ▼ greater less than 0.05. ​(Round to four decimal places as​ needed.)
