Egg Incubation Times The mean incubation time of fertilized chicken eggs kept at 100.5°F in a still-air incubator is 21 days. Suppose that the incubation times are approximately normally distributed with a standard deviation of 1 day. Source: University of Illinois Extension

(a) Draw a normal model that describes egg incubation times of fertilized chicken eggs.

(b) Find and interpret the probability that a randomly selected fertilized chicken egg hatches in less than 20 days.

(c) Find and interpret the probability that a randomly selected fertilized chicken egg takes over 22 days to hatch.

(d) Find and interpret the probability that a randomly selected fertilized chicken egg hatches between 19 and 21 days.

(e) Would it be unusual for an egg to hatch in less than 18 days? Why?
