1 point) Empathy means being able to understand what others feel. To see how the brain expresses empathy, researchers recruited 16 couples in their midtwenties who were married or had been dating for at least two years. They zapped the man's hand with an electrode while the woman watched, and measured the activity in several parts of the woman's brain that would respond to her own pain. Brain activity was recorded as a fraction of the activity observed when the woman herself was zapped with the electrode. The women also completed a psychological test that measures empathy.

Given that the equation for the regression line is y ANSWERExplanation / Answer
y = 0.00733 * x - 0.06057
For subject 2, empathy score = 52
Thus, predicted brain activity:
= 0.00733 * 52 - 0.06057
= 0.32059
observed value of y for sub 2 is 0.391
The difference between the observed value of the dependent variable (y) and the predicted value () is called the residual (e).
Each data point has one residual
.Residual = Observed value - Predicted value.
e = y -
=0.391 - 0.32059
=0.07041
Rounding to theree decimal places.
e = 0.070
