Research reported the results of a study on the occurrence of oxygen and chloride in surface streams in central Washington state area. The following data are chloride concentration y (in milligrams per liter) and roadway area in the watershed x (in percentage) y 19.20 23.10 27.40 27.70 31.80 39.50 X 0.69 1.30 1.05 1.06 1.74 1.62 y 4.40 6.60 9.70 10.60 10.80 10.90 X 0.19 0.15 0.57 0.70 0.67 0.63 y 11.80 12.10 14.30 14.70 15.00 17.30 X 0.47 0.70 0.60 0.78 0.81 0.78 ✓ Fit the simple linear regression model using the method of least squares ✓ Find an estimate of 2 ✓ Estimate the mean chloride concentration for a watershed that has 1% roadway area ✓ Find the fitted value corresponding to x = 0.47 Find the associated residual ✓ Test the hypothesis, with a = 0.01 H₁: B₁ = 0 H₁: B₁0 Estimate the standard errors in ¹B₁ ✓ Find a 99% prediction interval on chloride concentration when roadway area x = 1.0% A. 2.14169 B. 1.93591 C. 1.6629 D.y = 0.470 + 20.567x E. 0.0997 + 0.0414x F. 21.038 G.
