Given the following measurements (Table 1) of traffic speed, v and density (concentration) k, set up a linear relationship to predict the speeds (km/h) given the density (veh/km). Also find the adjusted R2 and standard error for the following data. 

Table 1 Speed, v (km/h) 50 45 40 30 25 16 12

      Density, k (veh/km) 10 20 36 39 70 90 100
