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.
if 100 fertilized eggs were randomly selected, 48 of them would be expected to hatch between 23 and 25 days.
would it be unusual for an egg to hatch in less than 22 days? Why?
