The thickness of photoresist applied to wafers in semiconductor manufacturing at a particular on the wafer is uniformly distributed between 0.2032 and 0.2147 micrometers. (a) Determine the proportion of wafers that exceeds 0.2125 micrometers of photoresist thickness. (Round your answer to 3 decimal places.) (b) Determine the mean of X (in micrometers) (Round your answer to 4 decimal places.) (c) Determine the variance of X (in micrometers2) (Round your answer to 8 decimal places.)
