A.
X Values
∑ = 90
Mean = 7.5
∑(X - Mx)2 = SSx = 143
Y Values
∑ = 161.54
Mean = 13.462
∑(Y - My)2 = SSy = 166.763
X and Y Combined
N = 12
∑(X - Mx)(Y - My) = -149.97
R Calculation
r = ∑((X - My)(Y - Mx)) /
√((SSx)(SSy))
r = -149.97 / √((143)(166.763)) = -0.971

You run a regression analysis on a bivariate set of data ( n = 41 ). With ¯ x = 41.6 and ¯ y = 31.1 , you obtain the regression equation y = − 2.748 x + 61.522 with a correlation coefficient of r = − 0.011 . You want to predict what value (on average) for the response variable will be obtained from a value of 10 as the explanatory variable. What is the predicted response value? You...
