The article “Measuring and Understanding the Aging of Kraft Insulating Paper in Power Transformers” (IEEE Electrical Insul. Mag., 1996: 28–34) contained the following observations on degree of polymerization, DP, for paper specimens for which the product of viscosity and concentration (factors of interest to the study) fell in a certain middle range: 418 421 421 422 425 427 431 434 437 439 446 447 448 453 454 463 465 Construct an interval estimate for the true mean degree of polymerization of paper specimens. Would it be reasonable to claim that the degree of polymerization is 450?
