Moisture content in percent by volume (x) and conductivity in mS/m (y) were measured for 50 soil specimens. The means and standard deviations were =8.1, s, = 1.2. 5 = 30.4, s, =1.9 . The correlation between conductivity and moisture was computed to be r = 0.85. Find the equation of the least-squares line for predicting soil conductivity from moisture content.
