The mean incubation time of fertilized eggs is 2222 days. Suppose the incubation times are approximately normally distributed with a standard deviation of 11 day. (a) Determine the 1919th percentile for incubation times. (b) Determine the incubation times that make up the middle 3939% of fertilized eggs. (a) The 1919th percentile for incubation times is 2121 days. (Round to the nearest whole number as needed.) (b) The incubation times that make up the middle 3939% of fertilized eggs are nothing to nothing days. (Round to the nearest whole number as needed. Use ascending order.)
