Question

The standard error =__________. ( s is the standard deviation of the sample, N is the population size, and n is the sample size. N >20n)
1. s/√n
2. s/√N
3. √(s/n)
4. √(s/N)

Answer 1

Correct Answer - Option 1 : s/√n

Explanation

When the standard deviation of the population is known( then for the large samples

Standard error = s/√n

s = standard deviation for large sample

n = number of obserbvations
