The mean incubation time for a type of fertilized egg kept at a certain temperature is 23 days. Suppose that the incubation times are approximately normally distributed with a standard deviation of 1 day.
Complete parts (a) through (e) below.
a. What are the values that would fall within 1 standard deviation; 2 standard deviations; 3 standard deviations of the mean incubation time
b. Find and interpret the probability that a randomly selected fertilized egg hatches in less than 22 days.
c. Find and interpret the probability that a randomly selected fertilized egg takes over 24 days to hatch.
d. Find and interpret the probability that a randomly selected fertilized egg hatches between 21 and 23 days.
