Use compass directions to describe the direction of the vector. The diagram is not drawn to scale. Please explain how you got the answer!!

I cannot transfer the diagram to here so I will describe it:
A vector is drawn lower left quadrant of plane formed by the intersection of the north south axis and the east west axis where north is up, east is right, south is down, and west is left. The angle adjacent above the vector and adjacent below the horizontal axis is 41 degrees.

Researchers are conducting experiments to determine the role of alcohol in the development of depression. after the study is complete, they determine that the relative risk of developing depression is 1.55 with a 95 % ci of 1.2 -1.9. each group is then divided into nonsmokers and smokers. the relative risk for the nonsmokers is 1.12 with a 95% ci of 0.87-1.37. the relative risk for the smokers is 1.7 with a 95 % cl of 1.5-1.9. what type of bias may affect this study? a. procedure bias b. recall bias c. selection bias d. confounding e. lead-time bias
