A regression and correlation analysis resulted in the following information regarding a dependent variable ( y) and an independent variable ( x). Σx = 90 Σ(y - )(x - ) = 466 Σy = 170 Σ(x - )2 = 234 n = 10 Σ(y - )2 = 1434 SSE = 505.98 The least squares estimate of the intercept or b0 equals a. -.923. b. 1.991. c. -1.991. d. .923.

Step 1
The formula is: b0 = Σy/n - b1*(Σx/n) Where: - Σy is the sum of the dependent variable values - n is the number of observations - Σx is the sum of the independent variable values - b1 is the slope of the regression line From the given information, we know that Show more…

A simple regression analysis of a sample of 10 observations resulted in the following information regarding a dependent variable (y) and an independent variable (x). ΣX = 90 ΣY = 170 Σ(X - X̄)² = 234 Σ(Y - Ȳ)(X - X̄) = -468 Σ(Y - Ȳ)² = 392 Σ(Y - Ŷ)² = 1400 The least squares estimate of b₁ equals Select one: a. -.334 b. 2 c. -2 d. 0.5

A regression and correlation analysis resulted in the following information regarding a dependent variable (y) and an independent variable (x). ΣX = 90 ΣY = 170 n = 10 SSE = 505.98 Σ (Y - Y bar )(X - X bar ) = 466 Σ (Y - Y bar)2 = 1434 Σ (X - X bar)2 = 234 Refer to Exhibit 12-9. The coefficient of determination equals 0 -0.6472 0.6472 1
