1. The Formula For A Regression Equation Is Y =

1. 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 for a person scoring 6 on X = 2*6 + 9 = 21b. If someone’s predicted score was 14, what was this person’s score on X?Here,14 = 2X + 9X = (14-9)/2 = 2.52. For the X,Y data below, compute:xy463751211171091421a. 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 = 0.849P-Value = 0.032The 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.
