The incubation time for a breed of chicks is normallydistributed with a mean of 24 days and standard deviation ofapproximately 3 days. Look at the figure below and answer thefollowing questions. If 1000 eggs are being incubated, how manychicks do we expect will hatch in the following time periods?(Note: In this problem, let us agree to think of a single day or asuccession of days as a continuous interval of time. Assume alleggs eventually hatch.) (a) in 18 to 30 days 950 chicks (b) in 21to 27 days chicks (c) in 24 days or fewer chicks (d) in 15 to 33days
