An experiment was conducted to determine the effect of machining factors on ceramic strength. Two levels of table speed (slow and fast), two directions (longitudinal and transverse) and two levels of wheel grit (I and II) were identified by the researcher. The experiment was replicated three times and the strength of each randomly selected ceramic was obtained. The ANOVA table of the results of the analysis are as follows. 1. Refer to the ANOVA table at a=0.01, what is the conclusion for testing significance in 3-way interaction Reject/Fail to Reject Ho 2. If sequential test of hypothesis is performed the following are (True or False)? a. All 2-way interaction effects are going to be tested b. All main effects are going to be tested 3. What combination of effects will result to a significant result at a=0.01 if should all test are going to be performed among the main effects and two way interactions? (choose 1pair/combination: direction, wheel grit, speed)
