Problem 5. (15 points) Use a scatterplot to determine whether there is a correlation between the two variables. (Note: don't need to calculate the linear correlation coefficient T!) x 0.9 1.8 2.7 3.7 4.8 5.7 6.7 7.2 8 9.2 y 0.9 1.8 2.7 3.7 4.8 5.7 6.7 7.2 8 9.2 There is O A. a perfect positive correlation between a and y O B. no correlation between a and y O C. a nonlinear correlation between a and y O D. a perfect negative correlation between a and y O E. a positive correlation between a and y O F. a negative correlation between T and y
