Question 1089001: You run a regression analysis on a bivariate set of data (n=98). You obtain the regression equation y=-3.992x+42.328 with a correlation coefficient of r=-0.312 (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 170 on the response variable.
What is the predicted explanatory value?
x =

y=-3.992x+42.328; y is the response variable.
170=-3.992x+42.328
127.672=-3.992x
x=-31.98 or -32.0
