Question

The table below gives data from a study that shows that social exclusion causes "real pain." That is, activity in the area of the brain that responds to physical pain goes up as distress from social exclusion goes up. The scatterplot for this data shows a moderately strong linear relationship. The data are given below Social Brain Social Brain Subject distress activity Subject distress activity 0,027 0.029 0.033 0.064 0.077 0.124 1.22 1.87 1.06 2.56 2.15 2.65 1.99 -0.055 0.0409 -0.02810 -0.01811 -0.01812 2.22 2.58 2.77 2.77 3.37 3.69 0.01813 0.021 (a) What is the equation of the least-squares regression line for predicting brain activity from social distress score? (Round your answers to four decimal places.) brain activity =-01218 X social distress-0.1218

Explanation / Answer

Coefficients

Term Coef SE Coef T-Value P-Value VIF
Constant -0.1225 0.0245 -5.01 0.000
social distress 0.05910 0.00985 6.00 0.000 1.00

Regression Equation

brain activity = -0.1225 + 0.05910 social distress
