Do you see any patterns on the graphs you created? Explain. (3 marks) 2. Do you think foot length can be used reliably to predict height? Using the foot length measurement that you collected from a classmate, compare this foot length measurement to the line of best fit on your graph to predict the height of your classmate. How close is the predicted height based on your graph to your classmate's actual height? Explain why the predicted height may or may not be close to the actual height. (6 marks) 3. Paleontologists use the ratio of stride length divided by leg length (S/L) to tell whether a dinosaur is walking, trotting, or running. Paleontologists use the following ratios to determine how a dinosaur might have been moving. If ratio is less than 2, it was probably walking; if between 2 and 2.9, it was trotting; if more than 2.9, it was likely running. (<2 >2.9 = running) Examine the ratios of stride to leg length (Sw/L and Sr/L) that you calculated in Table 2 to see if the values in the above chart would also apply to humans. If not, what values would
