n = [((Za/2)sigma)/E]2
n = sample size
(Za/2) = critical value
sigma = population standard deviation
E = margin of error
This formula can be used when you know sigma and want to determine the necessary sample size to establish, within a confidence of 1-a, the population mean to within +-E.
I won't go into the details of explaining it, because the site I myself am reviewing from right now has an excellent explanation, and I strongly suggest reading through it. Visit it here.

The formula for calculating the unemployment rate is: (Number of unemployed individuals / Labor force) * 100. This formula can be applied to different groups by using the corresponding numbers for each group (e.g., number of unemployed individuals and labor force for a specific demographic).
