Initially, a population is 500, and it grows by 2% each year. Explain why the population is an exponential function of time.

Find a formula for the population at any time. (Let t represent time in years and P represent the population size.)

Determine the population size after 5 years. (Round your answer to the nearest whole number.)

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
