Answer: Approximately 2.33</h3>
The variance is given to be 5.43
Apply the square root to the variance to get the standard deviation
s = standard deviation
v = variance
s = sqrt(v)
s = sqrt(5.43)
s = 2.330326 which is approximate
s = 2.33
I rounded to 2 decimal places as this is the number of decimal places used for the variance.
