The incubation time for a breed of chicks is normally distributed with a mean of 28 days tandard deviation of approximately 3 days. Look at the figure belowa estions. If 1000 eggs ar being incubated, how many chicks do we expect will hatch in the following time periods? (Note: In this problem, le erval of time. Assume all eggs eventually hatch.)
