Choose the correct graph below. OA O B. OC OD 20- 20 a 20- a O Q (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 ) Click to select your answers) statCrunch Type here to search O
