Casey read a report that said the probability that a randomly selected American is left-handed is 14%, percent. She was curious how many left-handed students to expect in a class of 30 students. She simulated 50 classes of 30 students where each student selected had a 0.140, point, 14 probability of being left-handed. Casey counted how many left-handed students were in each simulated class.

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
