The incubation time for a breed of chicks is normally distributed with a mean of29days and standard deviation of approximately2days. Look at the figure below and answer the following questions. If1000eggs 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.)
