- The photoresist thickness is one the quality characteristic in intagre circuits . A new process has been developed for applying photoresist to 125-mm silicon wafers used in manufacturing integrated circuits Twelve wafers were tested and the following photoresist thickness measurements were observed 13.3987, 13.3957, 13.3902, 13.4015 , 13.4001 13.3918, 13.3965, 13.3925, 13.3946 , 13.3939, 12.4005 and 13.4002 Assume that thickness is normally distributed a) Test the hypothesis that mean thickness is 13.4x1000 A. Use a = 0.05 and assume a two-sided alternative b ) Find a 99% two-sided confidence interval on mean photoresist thickness c) Find a 95% two-sided confidence interval on standard deviation of photoresist thicknessAverage rate pleaseDiscuss the idea of calculating the area of the region using the Mean value Theorem. Include examples that will make the explanation clear and concise.
