The incubation time for a breed of chicks is normally distributed with a mean of29days and standard deviation of approximately3days. 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.)(a) in23to35days chicks (b) in26to32days chicks (c) in29days or fewer chicks (d) in20to38days chicks
