The incubation time for a breed of chicks is normally distributed with a mean of 21 days and standard deviation of approximately 3 days. Look at the figure below and answer the following questions. If 1000 eggs are being incubated, how many chicks do we expect will hatch in the following time periods? (Note: In this problem, let us agree to think of a single day or a succession of days as a continuous interval of time. Assume all eggs eventually hatch.)
a 15 to 27 days
b 18 to 24 days
c in 21 days or fewer
d 12 to 31 days
