For the data in Exercise 1 of Chapter 10, the .95 confidence interval for the slope, based on the least squares regression line, is (0.0022, 0.0062). Using R, the .95 confidence interval for the slope returned by lsfitci is (0.003, 0.006). The .95 confidence interval returned by both R and the S-PLUS function regci (using the Theil–Sen estimator) is (0.003, 0.006). Verify this result.
