Answer #1

Chi-Square Test

Observed Frequencies
	Column variable			Calculations
Row variable	C1	C2	Total	fo-fe
rowA	35	83	118	-3.57692	3.576923
row B	33	57	90	3.576923	-3.57692
Total	68	140	208

Expected Frequencies=Σrow*Σcolumn/Σgrand total
	Column variable
Row variable	C1	C2	Total	(fo-fe)^2/fe
rowA	38.577	79.423	118	0.332	0.161
row B	29.423	60.577	90	0.435	0.211
Total	68	140	208

Chi-Square Test Statistic =Σ(fo-fe)^2/fe = 1.139
