Suppose the lengths of human pregnancies are normally distributed with 266 days and a = 16 days. Complete parts (a) and (b) below. (a) The figure to the right represents the normal curve with = 266 days and = 16 days. The area to the left of X=240 is 0.0521. Provide two interpretations of this area. Provide one interpretation of the area using the given values. Select the correct choice below and fill in the answer boxes to complete your choice. (Type integers or decimals.) OA. The proportion of human pregnancies that last more than days is 240 266 OB. The proportion of human pregnancies that last less than days is Provide a second interpretation of the area using the given values. Select the correct choice below and fill in the answer boxes to complete your choice. (Type integers or decimals.) OA. The probability that a randomly selected human pregnancy lasts more than days is OB. The probability that a randomly selected human pregnancy lasts less than days is (b) The figure the right represents the normal curve with =266 days and = 16 days. The area between x = 280 and x = 300 is 0.1740. Provide two interpretations of this area. Provide one interpretation of the area using the given values. Select the correct choice below and fill in the answer boxes to complete your choice. (Type integers or decimals. Use ascending order.) A OA. The proportion of human pregnancies that last less than or more than 266 280 300 days is OB. The proportion of human pregnancies that last between and days is Provide a second interpretation of the area using the given values. Select the correct choice below and fill in the answer boxes to complete your choice. (Type integers or decimals. Use ascending order.). OA. The probability that a randomly selected human pregnancy lasts less than or more than days is OB. The probability that a randomly selected human pregnancy lasts between and days is Z
