Karr and Coats studied the effects of several chemicals on the growth of the German cockroach. the following table gives their data for the percent of the chemical ?-terpineol in the diet of 20% ?-terpineol. Percent ?-terpineol 1 10 25 Days to Adult Stage 129 113 115 A. On the basis of the data given in the table, find the best-fitting logarithmic function using least squares. State the square of the correlation coefficient. (Use 4 decimal places in your answer.) y(x) = r2 = B. Use this model to estimate the days to adult stage with a diet of 20% ?-terpineol. (Round to the nearest day.) When a 20% ?-terpineol, then there are days to adult stage.
