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. Click here to view the data set. Click here to view the critical values table. (a) Draw a scatter diagram of the data. Choose the correct graph below. O A. O B. O C. OD. 20- 20- 20- T 20- O O O O 0- 0- O (b) By hand, compute the correlation coefficient. The correlation coefficient is r= . (Round to three decimal places as needed.) (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,, linear relation exists between x and y. (Round to three decimal places as needed.) X Data set + CO Next Print Done
