You run a regression analysis on a bivariate set of data (n = 10). You obtain the regression equation y = 0.493x + 58.349 with a correlation coefficient of r = 0.877 (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 100 on the response variable. What is the predicted explanatory value? X = (Report answer accurate to one decimal place.)
