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 correlation 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.
