Yоu hаve а prоcess аnd yоu know from extensive past experience that the population average is 21 and the population standard deviation is 1.48. You are testing a potential substitute from a potential supplier that is offering a lower price. You are interested in the change assuming the quality is equal to or greater than your current suppliers material. If the average is statistically significantly higher than the population average of 21 then you will accept the new supplier with their material.
