The line width for semiconductor manufacturing is assumed to be normally distributed with a mean of 0.5 micrometre and a standard deviation of 0.04 micrometre. (a) What is the probability that a line width is greater than 0.62 micrometer? ANSWER: The probability that a line width is greater than 0.62 micrometer is P(X > 0.62) = (b) What is the probability that a line width is between 0.47 and 0.63 micrometer?
