A2)
An article described an experiment in which several different types of boxes were compared with respect to compression strength (in pounds). The data in the table below resulted from a single-factor
experiment involving k 4 types of boxes (the sample means and standard deviations are in close agreement with values given in the paper). Do these data provide evidence to support the claim that
the mean compression strength is not the same for all four box types? Test the relevant hypothesis using a significance level of 0.01 if 682.5042.
