Egg Incubation Times The mean incubation time of fertilized chicken eggs kept at 100.5°F in a still-air incubator is 21 days. Suppose that the incubation times are approximately normally distributed with a standard deviation of 1 day. Source: University of Illinois Extension
(a) Determine the 17th percentile for incubation times of fertilized chicken eggs.
(b) Determine the incubation times that make up the middle 95% of fertilized chicken eggs.

Definition The One-Sample Sign Test is a nonparametric test that uses data, converted to plus and minus signs, to test a hypothesis regarding the median of a population. Data values equal to the assumed value of the median are ignored during the test. For example, suppose we have the following set of data:
