x 2 6 6 7 9 y 3 7 6 9 5 Determine whether there is a linear relation between x and y. Because the correlation coefficient is â–¼ and the absolute value of the correlation coefficient, enter your response here, is â–¼ than the critical value for this data set, enter your response here, â–¼ no a negative a positive linear relation exists between x and y. (Round to three decimal places as needed.)
