Consider the following table of data. x 0 1 2 y 4 1 0 1 3 4 1 4 (a) Calculate the least squares line and the correlation coefficient. (b) Sketch a graph of the data. (c) Comparing your answers to parts (a) and (b), does a cor- relation coefficient of 0 mean that there is no relationship between the x- and y- values? Would some curve other than a line fit the data better? Explain.
