Basic Math

Smitley and Davis studied the changes in gypsy moth egg massdensity over one generation as a function of the initial egg massdensity in a control plot and two treated plots. The data below arefor the control plot.
Initial Egg Mass (per 0.04 ha) 50 75 100 160 175 180 200
Change in Egg Mass Density (%) 250 -100 -25 -25 -50 50 0

A. On the basis of the data given in the table, find thebest-fitting logarithmic function using least squares. State thesquare of the correlation coefficient. (Note that the authors usedlogarithms to the base 10.) (Use 4 decimal places in youranswers.)
y(x) =

r² =

B. Use this model to estimate the change in egg mass density withan initial egg mass of 120 per 0.04 ha. (Use 4 decimal places inyour answer.)
With an initial egg mass of 120 per 0.04ha, the change in massdensity is
