The variables xp and yp have both been declared as pointers to integers, and have been assigned values (i. e., they are each pointing to an integer value). Write the code to exchange the values of these two variables (so that after the swap xp points to what yp originally pointed to and vice-versa-- in other words, in this exercise, you are swapping the pointers). Declare any necessary variables.

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
