Explanation:

The concept of percentile ranking is used here. The \(k\)th percentile of a data set is the value such that \(k\%\) of the data values are less than or equal to that value. In the context of employee evaluation, if an employee is in the 84th percentile, it means that 84% of the employees have an evaluation rating that is less than or equal to (i.e., this evaluation rating or worse) the rating of the employee in question.

Answer:

84% of employees have this evaluation rating or worse
