Carry out a multiple-comparison analysis to determine which, if any, of the four pre-load conditions are significantly
different from each other in their resulting strength.
What assumptions are necessary for the ANOVA to be valid? Do these assumptions seem to be satisfied by this particular
set of data? Explain your answer.
