The table below shows the radius y, in centimeters, created by growing algae in x days: Time (x) (days) 2 4 6 8 Radius (y) (cm) 4 7 10 14 Part A: What is the most likely value of the correlation coefficient of the data in the table? Based on the correlation coefficient, describe the relationship between time and radius of the algae. [Choose the value of the correlation coefficient from 1, 0.97, 0.5, 0.02.] (4 points) Part B: What is the value of the slope of the graph of radius versus time between 6 and 8 days, and what does the slope represent? (3 points) Part C: Does the data in the table represent correlation or causation? Explain your answer. (3 points)
