Answer:
The answer is 4
[tex]s = \sqrt{\frac{\Sigma^n_i_=_1(x_i-x)^2}{n-1} }[/tex]
Turn the equation into a simpler form
[tex]s = \sqrt{\frac{SS}{n-1} }[/tex]
[tex]s = \sqrt{\frac{64}{5-1} }[/tex]
[tex]s = \sqrt{\frac{64}{4} }[/tex]
[tex]s = \sqrt{16}[/tex]
That said, we know the square root of 16 is 4, so 4 would be your answer.
[tex]s = 4[/tex]
