Six Sigma Interpretation; Spreadsheet Application To what (one-tailed) probabilities do each of the following sigma level correspond, based on a standard normal curve: 3 sigma, 4 sigma, 5 sigma, and 6 sigma? (Hint: Use the NORM.DIST function in Excel. Note that this function returns the standard normal cumulative distribution function—that is, you will generate a one-tail probability associate with each listed sigma value. The distribution has a mean of 0 (zero) and a standard deviation of 1.) Round one-tailed probabilities (percentages) to 7 decimal places (e.g., 2.1845423%). Check Figures: For 3 sigma, the one-tailed probability equals 0.2699796%; for 6 sigma, the onetailed probability level is 0.0000002%. (2). To what level of defects per million do each of the onetailed probabilities correspond to? (Round answers to 3 decimal points.) (3). What is the point of these calculations?
