12.3:The Regression line and Prediction You run a regression analysis on a bivariate set of data (n = 43). You obtain the regression equation y = 1.501x + 5.518 with a correlation coefficient of r = 0.894 (which is significant at ? = 0.01). You want to predict what value (on average) for the explanatory variable will give you a value of 30 on the response variable. What is the predicted explanatory value? x = (Report answer accurate to one decimal place.)

Step 1

The regression equation is y = 1.501x + 5.518. So, we rearrange it to: x = (y - 5.518) / 1.501 Show more…

You run a regression analysis on a bivariate set of data (n = 43). You obtain the regression equation y = 1.501x + 5.518 with a correlation coefficient of r = 0.894 (which is significant at α = 0.01). You want to predict what value (on average) for the explanatory variable will give you a value of 30 on the response variable. What is the predicted explanatory value?
