Consider the curve y = 2 log x, where log is the natural logarithm. let l be the tangent to that curve which passes through the origin, let p be the point of contact of l and that curve, and let me be the straight line perpendicular to the tangent l at p. we are to find the equations of the straight lines l and m and the area s of the region bounded by the curve y = 2 logx, the straight line m, and the x-axis.

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
