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. 20- 20- (b) hand, compute the correlation coefficient. The correlation coefficient is r=969. (Round to three decimal places as needed.) (c) Determine whether there is a linear relation between x and y. Because the correlation coefficient is (positive, negative) and the absolute value of the correlation coefficient, ), is (greater, not greater) than the critical value for this data set, O. (positive, negative, no) linear relation exists between x and y. (Round to three decimal places as needed.)
