Question
100% to Wed 7:18 PM a LD DE The table below gives data from a study that distress from social exclusion goes up. The scatterplot for this data shows a moderately strong linear relationship. The data are given below that social exclusion causes "real pain." That is, activity in the area of the brain that to physical pain goes up as Subject distress activity Subject distress activity 2.20 0.029 2.48 0.031 2.77 0.033 2.77 0.064 .31 .077 3.63 0.124 1.28 -0.0S5 8 1.870.040 9 1.06 0.030 10 2.46 -0.018 11 2.19 -0.018 12 2.69 0.018 13 2.03 0.021 of the least-squares regression line for predicting brain activity from social distress score?
