Answer 1

	Cherry Jalopies Inc (X)	Straw Construction Company (Y)		(X -Average Return of X)^2	(Y -Average Return of Y)^2
Year 1	16	16		54.76	36
Year 2	11	23		5.76	169
Year 3	-1	-6		92.16	256
Year 4	6	6		6.76	16
Year 5	11	11		5.76	1
Total	43	50		165.2	478
Average Return =	Total Return / NO of years
	43 / 5	50 / 5
	8.60	10.00
Variance =	[((X -Average Return of X)^2) / n ]	[((Y -Average Return of Y)^2) / n ]
	165.2 / 5	478 / 5
	33.04000	95.60000
Standard Deviation =	Square root of Variance	Square root of Variance
	Square root of 33.04	Square root of 95.60
	5.75	9.78
