Suppose we are testing whether the number of geese that fly over a pond during the Spring explains the thickness of the ice in the pond the next winter. We collect data and find that the correlation coefficient is zero. We know that this Spring 2,853 geese flew over the pond, what is our best guess from this data as to the thickness of the ice next winter?

A.One standard deviation below the average thickness

B.One standard deviation above the average thickness

C.One standard deviation to the right of the average thickness

D.The average thickness
