The scatter plot above shows the pH of seven well water samples in West Texas with respect to the bicarbonate concentration in ppm (parts per million). The line of best fit is also shown.

According to the scatter plot, which of the following statements about the relationship between a well's pH and its bicarbonate concentration is true?

• A well with half as much bicarbonate as another well will have a pH twice that of the other well

• Wells that have more bicarbonate tend to have a higher pH

• Wells that have more bicarbonate tend to have lower pH

• The bicarbonate concentration of the well water is unrelated to its pH
