For the accompanying data set, (a) draw a scatter diagram of the data, (b) by hand, compute the correlation coefficient, and (c) determine whether there is a linear relation between x and y. Draw a scatter diagram of the data. By hand, compute the correlation coefficient. The correlation coefficient is r=enter your response here. (Round to three decimal places as needed.) Part 3 (c) Determine whether there is a linear relation between x and y. Because the correlation coefficient is and the absolute value of the correlation coefficient, is than the critical value for this data set, no linear relation exists between x and y.
