You run a regression analysis on a bivariate set of data (n=12n=12). You obtain the regression equation
y=0.631x+48.011y=0.631x+48.011
with a correlation coefficient of r=0.875r=0.875 (which is
significant at α=0.01α=0.01). You want to predict what value (on
average) for the explanatory variable will give you a value of 180
on the response variable.
What is the predicted explanatory value?
x =
(Report answer accurate to one decimal place.)
Homework Answers
Answer #1
Running a regression analysis on a bivariate data, we obtain the regression equation
Now, it is given that the value of the response variable is 180; we have to find the value of the explanatory variable.
So, we can say that
So, the value of the explanatory variable, correct to one decimal place is 209.2.
