  The mean incubation time of fertilized eggs is 23 days. Suppose that the incubation times are approximately normal with a standard deviation of 1 day.  a. Determine the 19th percentile for incubation times. Use 2 decimal digits. Present the graph with the distribution and locate the 19th percentile on the graph.  b. Determine the incubation times that make up the middle 97% of fertilized eggs. Use 2 decimal digits. Present the graph with the distribution and locate the middle 97% on the graph.
