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?

The accompanying summary data on compression strength (lb) for 12X10X8 in. boxes appeared in the article “Compression of Single-Wall Corrugated Shipping Containers Using Fixed and Floating Test Platens” (J. Testing and Evaluation, 1992: 318–320). The authors stated that “there was no significant difference in the variance of compression strength using fixed and floating platen method found at the 95% level.”  If you are allowed to assume the distribution of the compression strength of the cardboard is approximately normal, do you agree with the findings of the article?
