Statistics

You run a regression analysis on a bivariate set of data (n=50). You obtain the regression equation

y=-3.365x +- 54.483y

with a correlation coefficient of r = -0.5 (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?

x = _______________________________
