You run a regression analysis on a bivariate set of data (n=99). You obtain the regression equation
y=0.843x+6.762
with a correlation coefficient of r=0.954 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 150 on the response
variable.
What is the predicted explanatory value?
