ou run a regression analysis on a bivariate set of data (n=65n=65). You obtain the regression equation
y=−1.915x+−54.061y=-1.915x+-54.061
with a correlation coefficient of r=−0.626r=-0.626 (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 30
on the response variable.
What is the predicted explanatory value?
x = _______
Answer
We have the regression equation
y = -1.915x -54.061
Now, we have to find the value of x when we have y = 30
so, setting y= 30 in the above equation
so, we get
30 = -1.915x - 54.061
adding 54.061 on each side, we get
30 + 54.061 = -1.915x -54.061 + 54.061............................here -54.061 and +54.061 will become 0
we get
84.061 = -1.915x
dividing both sides by -1.915
we get
(84.061)/(-1.915) = (-1.915x)/(-1.915)..........................here (-1.915)/(-1.915) becomes 1
so, we get
-43.896 = x
So, the required value of explanatory variable x is -43.896
