Question 1139218: The mean incubation time for a type of fertilized egg kept at 100.3 degrees Fahrenheit is 21 days. Suppose that the incubation times are approximately normally distributed with a standard deviation of 2 days. Determine the probability that a randomly selected fertilized egg takes over 25 days to hatch.

z=(x-mean)/sd
>(25-21)/2=+2
probability z>2=0.0228
