From these data, you can safely infer (Choose the best answer) A. Septic tanks appear to contribute to the Counties ground water nitrate concerns. However, additional factors are also involved and need to be investigated. B. Septic tanks have increased nitrate concentration by 15%. Therefore, restricting future septic tank installations is important for the counties ground water quality. C. Septic tanks have increased nitrate concentration by 15%. Therefore, restricting futu re septic tank installations is important for the counties ground water quality. In addition, the County needs to seriously consider extending existing sewer lines to thereby reduce the number of septic tanks. D. The correlation coefficient of 0.15 is very low and fails to show any correlation between septic tanks and the Counties ground water concerns regarding nitrates. - A Which scale representation format remains accurate when the final map product is not reproduced at the same page size it was designed for?
