The table has been created just we need the formula to utilise

The formula is given by

[tex]\\ \rm\Rrightarrow \sigma=\sqrt{\dfrac{\sum f(x-\overline{x})^2}{n}}[/tex]

  • Find f(x-x^-)²

It's

  • 313.29+806.45+474.32+72.9+58.19+532.9+605.16+0+497.29
  • 3360.5

Now

[tex]\\ \rm\Rrightarrow \sigma=\sqrt{\dfrac{3360.5}{50}[/tex]

[tex]\\ \rm\Rrightarrow \sigma=\sqrt{67.21}[/tex]

[tex]\\ \rm\Rrightarrow \sigma=8.2[/tex]
