For the stage-discharge data in Table Q6, fit a regression equation for use in estimation of stage for a known value of discharge. i. Develop a gauge(stage)-discharge relationship for this stream at this section (using graph paper). ii. Predict the coefficient of correlation of the derived relationship. iii. Based on the equation derived, determine the stage for a discharge of 2000 m/s.
