sum	6702	9307	37559.5	78663.875	52516.75
mean	837.75	1163.375	sxx	syy	sxy

SSR	sxy^2/sxx=	73430.39792
SST	syy=	78663.875
R^2	SSR/SST	0.933470388

# The coefficient of determination is 0.933

Interpretation:

The percentage of variation in variable y i.e average weekly wages (federal) that is explained by least square regression line is 93.3%
