Suppose the lengths of human pregnancies are normally distributed with (backward 4)=266 days and (zero with a tail)=16 days
The figure to the right represents the normal curve 266 and 16 days the area to the left of x=250 is 0.1587 provide two interpretations of this area?

B) the proportion of human pregnancies that last more than ? Days is?
A) the proportion of human pregnancies that lasts less than 250 days is 0.1587
B) the proportion of human pregnancies that last more than 250 days is 0.8413
