Required information To assess the effect of piston ring type and oil type on piston ring wear, three types of piston ring and four types of oil were studied. Three replications of an experiment, in which the number of milligrams of material lost from the ring in four hours of running was measured, were carried out for each of the 12 combinations of oil type and piston ring type. With oil type as the row effect and piston ring type as the column effect, the following sums of squares were observed: SSA = 1.0926, SSB=0.9340, SSAB - 0.2485, SSE - 1.7034 d Is it plausible that the main effects of all type are all equal to 0? Provide the value of the test statistic and the P-value. The test statistic is 0.5835 Since 0.001<P < 0.01 it is not plausible that the main effects of oil type are all equal to 0.
