For this data, ?x = 9.125 and SSxx = 266.875. The followingoutput is obtained from minitab.

Regression Analysis : y versus x

The regression equation is: y = ?2.61?1.674x

Predictor	Coefficient	SE Coefficient	T	P
Constant	-2.61	9.839	*	*
x	-1.674	0.911	*	*

(a). Give an interpretation of the slope of the least squaresline. Over what range of x is the interpretation meaningful?

(b). Conduct a test to determine if the slope parameter issignificant at the .05 level of significance. Clearly state all 5steps.

(c). Find a 95% confidence interval for the slope parameter andinterpret it.
