The Normal modelN(270,9) describes the length of pregnancies, in days, for women who go into spontaneous labor. Which of these statements is asking for a measurement (is an inverse Normal question) and which is asking for aprobability?
A. If 60% of women have a pregnancy length below this number of days, what is the number of days?
B. If we select, at random, a woman who goes into spontaneous labor, what is the probability that her pregnancy will be 279 days or fewer?
