If X is a binomial random variable, then SD(X) (standard deviation of X) can be calculated using the following formulas:
1) np(1−p)
2) np(1−p)⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯√ (square root of np(1−p))
3) σ (sigma, population standard deviation)
4) σ2 (sigma squared, population variance)
So, the correct options from the given list are:
- np(1−p)
- np(1−p)⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯√
- σ2
- σ
