A Baker Must Monitor the Temperature at Which Cookies Are

question 16

Short Answer

A baker must monitor the temperature at which cookies are baked. Too much variation will cause inconsistency in the texture of the cookies. Past records show that the variance of the temperatures has been 1.44 degrees. A random sample of 30 batches of cookies is selected, and the sample variance of the temperature is 4.41 degrees. Test the hypothesis that the temperature variance has increased above 1.44 degrees at α = .05.
