5. Below is a graph from a study on fish mercury concentration by weight. 0.9 0.8 0.7 0.6 0 .5 Weight of specimen (kg 0.4 0.3 0.2 0.1 O 0.05 0.1 0.15 0.2 0.25 Total mercury (mg/kg) for dry weight y = 3.5543x + 0.0217 R2 = 0.9319 a. How much total mercury would a fish that weighs 0.5 kg (dry weight) have? Show your work. (2 point) Answer: N b. What can we say about the mercury concentration of a fish that weighs 10 kg given the above graph? (Hint: Think about limitations of extrapolation). (1 point) Answer: c. What does the R2 value indicate? (1 point)
