The аccоmpаnying summаry data оn cоmpression 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?
