I need help with last question please

Suppose the lengths of human pregnancies are normally distributed with u = 266 days and o = 16 days. Complete parts (a) and (b) below. O A. The probability that a randomly selected human pregnancy lasts more than days is B. The probability that a randomly selected human pregnancy lasts less than 280 days is 0.8106 (b) The figure to the right represents the normal curve with u = 266 days and o = 16 days. The area between x = 280 and x = 305 is 0.1834. 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.) O A. The proportion of human pregnancies that last between 280 and 305 days is X 266280 305 O B. The proportion of human pregnancies that last less than or more 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. Use ascending order.) A. The probability that a randomly selected human pregnancy lasts less than or more than days is O B. The probability that a randomly selected human pregnancy lasts between and days is
