The predicted score for a person scoring 6 on X 26 9 21 b. If someones predicted score was 14, what was this persons score on X Here, 14 2X 9 X (14-9)/2 2.5 2. For the X,Y data below, compute xy463751211171091421 a. r and determine if it is significantly different from zero. The obtained MINITAB output is given below, Correlation x, y Pearson correlation of x and y 0.849 P-Value 0.032 The r value is 0.849. And the p-value is 0.032 which is smaller than 0.05 indicating that r significantly different from zero. b. the slope of the regression line and test if it differs significantly from zero. The obtained output is given below, Regression Analysis y versus x Analysis of Variance Source DF Seq SS Contribution Adj SS Adj MS F-Value P-Value Regression 1 126.92 72.11 126.92 126.92 10.34 0.032 x 1 126.92 72.11 126.92 126.92 10.34 0.032 Error 4 49.08 27.89 49.08 12.27 Total 5 176.00 100.00 Model Summary S R-sq R-sq(adj) PRESS R-sq(pred) 3.50283 72.11 65.14 96.7406 45.03 Coefficients Term Coef SE Coef 95 CI T-Value P-Value VIF Constant 3.12 3.11 (-5.51, 11.75) 1.00 0.372 x 1.133 0.352 (0.155, 2.111) 3.22 0.032 1.00 Regression Equation y
