The concentration of impurities in a semiconductor used in the production of microprocessors for computer is a normally distributed random variable with mean 127 ppm and standard deviation 22. A semiconductor is acceptable only if its concentration of impurities is below 150 ppm. What proportion of the semi conductors are acceptable for use? The area under the standard normal curve for the value of z = 1.5 is 0.668. How can we solve this problem sir pls reply
