Me victor, vladimir , and vivian each has a different set of data points. each used the linear regression feature of his/her graphing calculator to find a linear function that models his/her data. the value of the correlation coefficient (r) associated with victors function was -0.91, the value or r for vladimir’s function was 0.73, the value of r for venus was -0.44, and the value of r for vivian’s function was 0.88. who has the best model for his or her data. a) venus b) victor c) vivian d) vladimir

B) Victor

Step-by-step explanation:

A positive value for r implies a positive linear correlation, while a negative value for r implies a negative linear correlation. The

closer |r| is to 1, the stronger the correlation, and the stronger the correlation, the more reasonable the data model. Since |–0.91| =

0.91, |0.73| = 0.73, |–0.44| = 0.44, and |0.88| = 0.88, the person with the most reasonable model for his or her data is B) Victor!

Hope this helps, have a good day. c;
