i. Complete the ANOVA table and show your working. ii. Based on your answer in (i), can you conclude that different factories have any significant effect on the strength of polypipes at 1% level of significance? iii. Suppose more samples are added to the study and the p-value is found to be 0.1235. Will you change the conclusion you have obtained in part (ii)? Justify your answer and state your new conclusion, if any.
