The table below shows the surface area y in square inches, of a shrinking puddle in x hours
time (x) (hours) 2 5 8 11

surface area (y) 25 15 9 2
(square inches)

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 surface are puddle. [choose the value of the correlation coefficient from -1,-0.99,-0.5,-0.02]

part b - what is the value of the slope of the graph of surface area versus time between 5 and 8 hours and what does the slope represent?

part c- does the data in the table represent correlation or causation?
