Refer back to the data in Exercise 4, in which y = ammo- nium concentration (mg/L) and x transpiration (ml/h). Summary quantities include n = 13, Ex, = 303.7, Ey, = 52.8, S = 1585.230769, S,, = -341.959231, and S, = %3D %3D yy 77.270769. a. Obtain the equation of the estimated regression line and use it to calculate a point prediction of ammo- nium concentration for a future observation made when ammonium concentration is 25 ml/h. b. What happens if the estimated regression line is used to calculate a point estimate of true average concentration when transpiration is 45 ml/h? Why does it not make sense to calculate this point estimate? c. Calculate and interpret s. d. Do you think the simple linear regression model does a good job of explaining observed variation in con- centration? Explain.
