a) The research question of this study is: What is the effect of varying room temperature on the productivity of workers in a factory? b) This experiment is a field experiment. This can be determined because the study is conducted in a real-world setting (a factory) rather than a controlled laboratory environment. c) The researcher cannot say with absolute certainty that the cooler room temperature caused the increase in productivity. This is because there may be other factors at play that could have influenced the results. For example, the workers' motivation, fatigue levels, or other environmental factors could have also affected their productivity. The potential issue in this experiment is the presence of confounding variables, which are variables that are not controlled or accounted for but could have an impact on the results.

Show your complete work. 1. Find the derivative of the following functions and simplify as much as possible: a. Y = 5X - 3X$^2$ + 4X$^3$ b. Y = (3X - 1)(3X$^3$ + X$^2$) Do not multiply. c. Y = (3X + 2X$^3$)/(X + 1) d. Y = 3X$^2$ - 2X$^3$ 2. Consider the following demand function: Q = 45 - (2/3)P Find the functional form of Marginal Revenue (MR) associated with this demand function. 3. Given the short-run cost function below. Find the functional form of Marginal Cost (MC). TC = 300 + 111Q - 7Q$^2$ + Q$^3$. 4. Use the following demand function and compute the value of price elasticity of demand when price (P) is equal to $5. Q = 60.5 - 2.87P
