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?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
