Comment on the article you read regarding the CDC on growth charts. Now read the following: A light bulb manufacturer keeps track of the length of use of its light bulbs that it produces by choosing random samples and testing. Why would they find it necessary to keep this data? Why would it be necessary to know this information? What would happen if a consumer purchased a package of light bulbs and three out of four of them burned out after 200 hours of use when the package states that each bulb should burn for 500 hours? Would you predict that the consumers would return the package for a refund or exchange them for another package from the same company?
