Answer:
Median
Step-by-step explanation:
Apply Definitions:
The mean is the average of all 830 lawyers salaries.
The minimum is the smallest salary among 830 lawyers salaries.
The mode is the salary which appears most often.
The median is the salary separating the higher half from the lower half of a data sample.
Old minimum = $0
New minimum = $x, which is still lower than any other salary. As we can see, the minimum has changed.
The mean has changed too, because if we change one number, the average of numbers cahnges.
The mode can change, because the smallest salary can appear most often, which means the smallest salary can be the mode.
Only the median remained the same, because new minimum salary doesn't change the number of salaries in a lower half.
