Homework Week7 Q.2. The formula for a regression equation is Y’ = 2X + 9. a. What would be the predicted score for a person scoring 6 on X? The predicted score =2*6+9=21 b. If someone’s predicted score was 14, what was this person’s score on X? The persons score on X =(14-9)/2=2.5 Q.6. For the X, Y data below, compute: a. r and determine if it is significantly different from zero. r=0.656 and the it is significantly different from zero. b. the slope of the regression line and test if it differs significantly from zero. The regression equation is Y = 3.81 + 0.833 X Predictor Coef SE Coef T P Constant 3.808 4.227 0.90 0.419 X 0.8331 0.4791 1.74 0.157 The slope of the regression is 0.8331 and the p value is 0.157>0.05 therefore it is not significantly differ from zero. c. the 95% confidence interval for the slope. The 95% confidence interval for the slope is (-0.497155842, 2.163260395) Q.5. At a school pep rally, a group of...
