Draw a normal curve, shade the area corresponding to the percent.2. Use table IV or a calculator (invNorm (5, 0, 1))to find the Z-Score that corresponds to the shaded area.3. Obtain the normal valueX =Examples:1. Egg Incubation TimesThe mean of the incubation time of fertilized chicken eggs kept at 100.5F in a still-air incubator is 21 days. Suppose the incubation times are approximately normally distributed with a standard deviation of 1 daySource: University of Illinois Extension.(a) Determine the 17th percentile for incubation times of fertilized chicken eggs.-81915-352425(b) Determine the incubation times that make up the middle 95% of fertilized chicken eggs?-212725-2305052. Medical ResidentsIn a 2003 study, the accreditation Council for Graduate Medical Education found that medical residents’ mean number of hours worked in a week is 81.7.
