Question 1147812: Suppose the lengths of the pregnanices of a certain animal are approximately normally distributed with a mean of u=161 and a standard deviation of 13 days.
What is the probability that a randomly selected pregnancy last less than 157 days? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! This is z=(x-mean)/sd or (157-161)/13 or z< (here) 4/13
That probability is 0.3792 using the fraction 4/13
