Q1) Experiment was performed to improve yield of chemical process. 4 factors were selected, and 2 replicates of completely randomized experiment were run. Results are shown in following table:

Treatment	Replicate	Replicate	Treatment	Replicate	Replicate
Combination	I	II	Combination	I	II
(1)	90	93	d	98	95
a	74	78	ad	72	76
b	81	85	bd	87	83
ab	83	80	abd	85	86
c	77	78	cd	99	90
ac	81	80	acd	79	75
bc	88	82	bcd	87	84
abc	73	70	abcd	80	80
