Please answer the question on the photo.
Transcribed Image Text:The article "Compression of Single-Wall Corrugated Shipping
Containers Using Fixed and Floating Test Platens" (J. Testing and
Evaluation, 1992: 318-320) describes an experiment in which
several different types of boxes were compared with respect to
compression strength (lb). The following STATISTICA output
displays the data for each of four box types: W, X, Y, and Z. The
data represent independent random samples from each box type
population. Since the sample sizes are all equal, this one-way
ANOVA is considered a balanced design.
They decide to make up six test specimens for each box type.
All 24 specimens are tested on a laboratory compression
strength tester in random order.
Here are the STATISTICA results for the post-hoc procedure.
