Answer #1

Least square regression line: y = 0.0008x - 1.8165

The linear regression model describes the dependent variable with a straight line that is defined by the equation Y = a + b × X, where a is the y-intersect of the line, and b is its slope.

	Intercept	-1.8165
Slope	Per capita Personal	0.0008

r-square: 0.85

R-squared denotes the positive linear relationship between the variables

Determine B is positive at 1 % significant level?

No , at 1% significant level , intercept is negative

Regression ? x Input Input Y Range: ок $B$1:$B$31 Cancel Input X Range: $A$1:$A$31 Help constant is Zero Labels Confidence Le

Summary output:

C D ELF G H J K L MN R BA/BS SUMMARY OUTPUT 19.5 y = 0.0008x - 1.8165 R2 = 0.8472 Regression Statistics Multiple R R Square A
