3.-/5 points BBBasicStat8 7.1.008.MI. The incubation time for a breed of chicks is normally distributed with a mean of 22 days and standard deviation of approximately 1 day. 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.)
