The variance calculated on 34 scores is equal to 14.94. what is the standard deviation?

ElenaW [278]

Since, the variance calculated on 34 scores is equal to 14.94.

We have to determine the standard deviation.

Relationship between Variance and standard deviation is:

Standard deviation = $\sqrt(Variance)$

Substituting the value of Variance, to evaluate the standard deviation.

We get,

Standard deviation = $\sqrt(14.94)$

= 3.865

= 3.87

Therefore, the standard deviation is 3.87

Perform the indicated operation.

Alexxx [7]

$\frac{2}{3} + \frac{3}{8} =$
$\frac{2 \times 8}{3 \times 8} + \frac{3 \times 3}{8 \times 3} =$
$\frac{16}{24} + \frac{9}{24} = \frac{25}{24} = 1 \frac{1}{24}$
So; the answer is: B 1 1/24.
