You run a regression analysis on a bivariate set of data (n = 101). You obtain the regression equation y = 4.436x - 29.838 with a correlation coefficient of r = 0.908 (which is significant at a = 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.)
