The mean incubation time for a type of fertilized egg kept at a certain temperature is 25 days. Suppose that the incubation times are approximately normally distributed with a standard deviation of 1 day. Find the probability that a randomly selected fertilized egg hatches between 23 and 25 days. The probability that a randomly selected fertilized egg hatches between 23 and 25 days is .4772.
Interpret this probability.
In every group of 100 fertilized eggs, how many eggs will hatch between 23 and 25 days?
