If a sample of 82 employees were taken from a population of 510 employees, could refer to the variance of how many of the employees salaries

82

Step-by-step explanation:

Given that a sample of 82 employees were taken from a population of 510 employees,

Here population size = 510

Sample size n = 82

Variance of sample will be only for the sample taken for 82 employees

Variance of sample will be denoted by s^2 and std deviation of sample = s

Std error of sample would be = variance s^2/sqrt of 82

Hence 82 is the right answer

The answer is B
