Please help me to solve it, just an answer will make sense, thank you!

Question 14 4 pts Can the depth of a water sample (in feet) help determine the arsenic level (in ppm, or parts per million) in the water. This question was investigated by randomly sampling 327 water samples and fitting the simple linear regression model, E(Y)=beta0+beta1X. The Statistix results are shown below: Descriptive Statistics Variable N Mean SD Minimum Maximum ARSENIC 328 95 . 360 111.98 1.0080 624.00 DEPTH 327 69.346 40.295 25.000 225.00 Least Squares Linear Regression of ARSENIC Predictor Variables Coefficient Std Error Constant 140.609 11.7820 11.93 0.0909 DEPTH 0.66943 0. 14696 -4.56 0. 0900 R2 0. 0600 Mean Square Error (MSE) 11431.9 Adjusted R2 0. 0571 Standard Deviation 106.920 AICC 3059.6 PRESS 3.75E+06 Cases Included 327 Missing Cases 1 Fill in the blanks to the following statement: We can explain of the variation in the sampled using the linear relationship provided by this model. 66%: arsenic levels 6%: arsenic levels 212%; arsenic levels O 5.7%; well depth values
