In sampling distribution, the formula of calculating standard deviation of sample proportion is as:

  • A Square root of \( \frac{p(1-p)}{n} \)
  • B Square root of \( pq / n \)
  • C Square root of \( ng / p \)
  • D Square root of \( pn/q \)

The correct answer is A. Square root of \( \frac{p(1-p)}{n} \)

The standard de....
