Answer:
Check being presented to the gender is the dependent variable
Which gender takes charge is the independent variable
Step-by-step explanation:
The relationship between two variables is found observing which variable changes the other.
When a variable changes irrespective of the other variable it is the independent variable.
When a variable changes with respect to the independent variable it is the dependent variable.
Here, the effect of who takes charge during dinner is being observed and whether this effect causes a change in who the check is presented to is noted.
Hence the check being presented to the gender is the dependent variable and which gender takes charge is the independent variable.
