Question
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 .01 if x = 683.7525. Type of Box Compression Strength (Ib) Sample Sample Mean SD 645.5 778.3 724.3 721.4 689.1 709.4 711.33 43.79 786.9 789.2 676.1 742.1 782.5 784.8 760.27 44.85 3 737.1 737.1 649.0 727.2 671.7 706.3 704.73 36.88 532.4 520.0 618.7 596.9 525.1 559.0 558.68 40.93 F = --Select--- V <P< --Select- v (Use Table 6 in Appendix A.) (Give the ansver to one decimal place.) The conclusion is the following. O reject Ho O fail to reject H.
