In a calibration for an instrumental method, a slope of 0.067 was obtained for the analyte, A. Potential interfering species B produced a slope of 0.034. The measurement error for the response was 0.0091 for both A and B. Compute the calibration sensitivity for the analyte. Answer to three decimal places. Compute the selectivity coefficient for the analyte, A, with respect to the interference, B. Answer to two decimal places.
