Question

what is the best point estimate for the population's standard deviation if the sample variance is 49.7? round your answer to one decimal place, if necessary.

Answer 1

Using the relation between standard deviation and variance it is concluded that the standard deviation for the population for the given variance is 7.1

What is the relation between standard deviation and sample variance?

In statistics, the two most crucial metrics are variance and standard deviation. While the variance is a measurement of how data points vary from the mean, standard deviation is a measure of the distribution of statistical data.

The square root of the variance yields the standard deviation, i.e.

Standard deviation = $\sqrt{variance$

Given that sample, the variance is 49.7 and we have to calculate the standard deviation.

Standard deviation (σ) = $\sqrt{variance$

= $\sqrt{49.7}$

= 7.0498

=7.1

Hence, the standard deviation for the population for the given variance is 7.1
