Question

The standard deviation of the data given by Variate (x) 0 1 2 3. . . . . n Frequency (f) $blank to the power of n end exponent C subscript 0 end subscript blank to the power of n end exponent C subscript 1 end subscript blank to the power of n end exponent C subscript 2 end subscript blank to the power of n end exponent C subscript 3 end subscript midline horizontal ellipsis times blank to the power of n end exponent C subscript n end subscript$

$\sqrt{\frac{(n + 1)}{2}}$
$\sqrt{\frac{n}{2}}$
$\frac{2^{n}}{n}$
$\frac{\sqrt{n}}{2}$

The correct answer is: $fraction numerator square root of n over denominator 2 end fraction$
