The population of grizzly bears in a remote area is modeled by the function P(t) = (200t - 120)/(t + 0.5) where t = 1 1represents the year 2001 t = 2 represents the year 2002and so onthe model to predict the number of grizzly bears born in the year 2018. (Use the table from

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
