The mean incubation time of fertilized eggs is 22 days. Suppose the incubation times are approximately normally distributed with a standard deviation of 1 day. (a) Determine the 10th percentile for incubation times. (b) Determine the incubation times that make up the middle 97% of fertilized eggs. . . . . . (a) The 10th percentile for incubation times is days. (Round to the nearest whole number as needed.) (b) The incubation times that make up the middle 97% of fertilized eggs are to days. (Round to the nearest whole number as needed. Use ascending order.)
