Shown below is a portion of an Excel output for regression analysis relating Y (dependent variable) and X (independent variable).

ANOVA / df / SS

Regression 1 / 2478.205

Residual 8 / 12036.195

Total 9 / 14514.400

Coefficients / Standard Error / t Stat / P-value

Intercept 140.68 / 83.280 / 1.689 / 0.130

X 49.17/ 38.312/ 1.283 / 0.235

1. What is the estimated regression equation that relates y to x?

2. Is the regression relationship significant? Use a p-value and alpha = 0.05?

3. What is the estimated value of y if x = 3.5?

4. Interpret the meaning of the value of the coefficient of determination if it is 0.17 in this case. Be very specific?
