A new process has been developed for applying photoresist to 125-mm silicon wafers used in manufacturing integrated circuits. Ten wafers were tested, and the following photoresist thickness measurements (in angstroms x1000) were observed: 13.3987, 13.3957, 13.3902, 13.4015, 13.4001, 13.3918, 13.3965, 13.3925, 13.3946, and 13.4002. (a) Test the hypothesis that mean thickness is 13.4 x 1000Å. Use = 0.05 and assume a two sided alternative. (b) Find a 99% two-sided confidence interval on mean photoresist thickness. Assume that thickness is normally...

Information for Problems 1 - 5: Photoresist is a light sensitive material used in industrial processes like photolithography and photoengraving to form a patterned coating on a surface. There are two types of photoresists: positive and negative. A positive photoresist is one in which the portion of the photoresist that is exposed to light becomes soluble to the photoresist developer. A negative photoresist is one in which the portion of the photoresist that is exposed to light becomes insoluble to...
