Tolerance in engineering is an allowance made for imperfections in manufactured objects. The manufacture of an oven specifies a temperature tolerance of 15ﾟF. This means that the temperature inside the oven will be within 15ﾟF of the temperature that is set on. Write and solve an absolute value equation to find the maximum and minimum temperature inside the oven when the thermostat is set on 400ﾟF

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
