Consider the following three statements:

Statement $2.$ Your friend tells you that he expects many people to stand at football games.

Statement $3$: An economist studies photos of many college football games and estimates that $75$ percent of all fans stand and $25$ percent sit.

Which of these statements deals with optimization, which deals with equilibrium, and which deals with empiricism? Explain.

Statement $1$ deals with

A$.$ optimization, because other fans are maximizing their well$-$being

B$.$ optimization, because you are choosing your best feasible option.

C$.$ empiricism, because you believe you know what the other fans will do

D$.$ equilibrium, because other fans may change their behavior.

Statement $2$ deals with

A$.$ equilibrium, because your friend presumes everyone is behaving optimally.

B$.$ empiricism, because your friend's prediction can be tested using data

C$.$ equilibrium, because it is a prediction rather than an observation

D$.$ optimization, because you will need this information to identify your best feasible option.

Statement $3$ deals with

A$.$ optimization, because it predicts how people's behavior will change

B$.$ empiricism, because it describes behavior using real$-$world data

C$.$ empiricism, because it illustrates people optimizing using cost$-$benefit analysis.

D$.$ empiricism, because it evaluates whether people maximize their well$-$being.
