88. The accompanying summary data on compression strength (lb) for 12  10  8 in. boxes appeared in the article Compression of Single-Wall Corrugated Shipping Containers Using Fixed and Floating Test Platens (J. Testing Eval., 1992: 318—320). The authors stated that the difference between the compression strength using xed and oating platen method was found to be small compared to normal variation in compression strength between identical boxes. Do you agree?
