Question

We often describe our emotional reaction to social rejection as "pain "A clever study asked whether social rejection causes activity in areas of the brain that are known to be activated by physical pain. If it does, we really do experience social and physical pain in similar ways. Subjects were first included and then deliberately excluded from a social activity while changes in brain activity were measured. After each activity the subjects filled out questionnaires that assessed how excluded they felt. A scatter plot shows a moderately strong linear relationship The figure below shows regression output from software for these data. From the software output what is the least squares regression equation? distress = -0.1261 + 0.0608(brain) brain = -0.1261 + 0.0608(distress) brain = 0.0608 - 0.1261(distress) brain = -0.1261 + 0.0246(distress) Use the following scatter plot from the regression analysis to answer.

Explanation / Answer

From the table, we see that the intercept is a = -0.1261 and the slope is b = 0.0608

The regression equation is y = a + bx

Brain = -0.1261 + 0.0608 * Distress

Option B
