Moisture content in percent by volume (x) and conductivity in ms/m (y) were measured for 76 soil specimens. the means and standard deviations were x- = 7.9, sx = 1.3, y- = 28.7, sy = 1.8. the correlation between conductivity and moisture was computed to be r = 0. 77. find the equation of the least squares line for predicting soil conductivity from moisture content. round the intercept to three decimal places and slope to four decimal places. the equation of the least square line, y = + x.
