The lengths of a particular animal's pregnancies are approximately normally distributed, with mean u= 271 days and standard deviation o = 20 days. (a) What proportion of pregnancies lasts more than 306 days? (b) What proportion of pregnancies lasts between 266 and 276 days? (c) What is the probability that a randomly selected pregnancy lasts no more than 246 days? (d) A "very preterm" baby is one whose gestation period is less than 221 days. Are very preterm babies unusual? Click the icon to view a table of areas under the normal curve. (a) The proportion of pregnancies that last more than 306 days is. (Round to four decimal places as needed.)
