Suppose the lengths of human pregnancies are normally distributed with p = 266 days and o = 16 days. Complete parts (a) and (b) below.
(a) The figure to the right represents the normal curve with u= 266 days and o = 16 days. The area to the left of X = 245 is 0.0947.
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.)
O A. The proportion of human pregnancies that last less than
days is
245 266
O B. The proportion of human pregnancies that last 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.)
A. The probability that a randomly selected human pregnancy lasts less than
days is
B. The probability that a randomly selected human pregnancy lasts more than
days is
