Answer :
The standard deviation is equal to the square root of the variance:
[tex]\sigma =\sqrt { Variance } [/tex]
Therefore:
[tex]\sigma =\sqrt { 88 } \\ \\ \therefore \quad \sigma \approx 9.4[/tex]
[tex]\sigma =\sqrt { Variance } [/tex]
Therefore:
[tex]\sigma =\sqrt { 88 } \\ \\ \therefore \quad \sigma \approx 9.4[/tex]
