Consider the following linear model for deer that has a time step of one year and includes three stage classes: fawn, yearling, and adult. F(1+1)) = .11 .15 25 F(t)
Y(1+1) = 0.5 0.1 0 Y (t)
A(1+1)) = 0 0.5 0.6 A(t)
a. What would it mean if the value in the upper right matrix element, 0.25, were increased to 2.0? Would the model still make biological sense?
b. The eigenvalues of this model modified as described in parteare: 1.122, 0.156+0.6221 and -0.156-0.6221. Has anything changed regarding the long-term survival of the deer population?

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
