Assuming three sigma quality performance, i.e. 0.9973 of the area under standard normal distribution curve falls within the specification limits. Suppose a product consists of an assembly of 60 independent components and all components must be non-defective for the product to work satisfactorily. Then the percentage of such products to be defective is approximately: Select one: a. 0.27% b. 15% c. 23.7% d. 2.7%
