Objective 2: Find the value of a Normal Random Variable The mean incubation time of fertilized eggs is 20 days. Suppose the incubation times are approximately normally distributed with a standard deviation of 1 day. Determine the 10th percentile for incubation times. Click the icon to view a table of areas under the normal curve The 10th percentile for incubation times is days. (Round to the nearest whole number as needed.)
