question 36

Multiple Choice

In simple regression analysis (Y = a + bX) ,the estimate of the slope coefficient b is equal to

• A) [\(\Sigma\)[(X_i - X_mean)(Y_i - Y_mean)] / \(\Sigma\)(X_i - X_mean)]².
• B) \(\Sigma\){[(X_i - X_mean)(Y_i - Y_mean)] / \(\Sigma\)(X_i - X_mean)}².
• C) \(\Sigma\) [(X_i - X_mean)(Y_i - Y_mean)] / \(\Sigma\)(X_i - X_mean)².
• D) \(\Sigma\) [(X_i + X_mean)(Y_i + Y_mean)] / \(\Sigma\) (X_i + X_mean)².
• E) \(\Sigma\) [(X_i - X_mean)(Y_i - Y_mean)] / \(\Sigma\)(X_i - X_mean).
