Question

what is the variance if the standard deviation is 1.63? 2.66 3.26 0.816 1.63

Explanation:

Step1: Recall variance - std dev relation

The variance $\sigma^{2}$ is the square of the standard - deviation $\sigma$.

Step2: Calculate variance

Given $\sigma = 1.63$, then $\sigma^{2}=1.63\times1.63 = 2.6569\approx2.66$.

Answer:

2.66
