Answer:
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
