Two bags A and B contain computer chips defective as well as non-defective, but the proportion of defective and non-defective chips is unknown. A sample of 55 chips selected with replacement from each of the bags, revealed 35 non-defective chips from A and 26 non defective from B. Using six steps process of hypothesis testing, test the hypothesis that (i) the two bags have equal proportion of non-defective chips, and (ii) A has a greater proportion of non-defective chips than B.
