Question 4 The thickness of a semiconductor is a critical factor in certain laptops. The process that makes semiconductors is considered under control if the standard deviation of the thickness is less than 0.6in. A random sample of 18 parts from a certain manufacturer has a thickness variance of 0.44in?. Conduct a test at the a=1% level if the process is not under control. (A) What are the null and alternative hypotheses? (B) What is (are) the critical values for this test? (C) What is the computed value of the test statistic? (D) What is your conclusion?
