Question

A sample of 16 people is taken and their weights are measured. The standard deviation of these 16 measurements is computed to be 5.8. What is the variance of these measurements?

Answer 1

The variance of given sample is 33.64 square pounds.

Explanation:

We are given the following in the question:

Sample size, n = 16

Standard deviation, s = 5.8 pounds

We have to find the variance of the given sample.

Variance is the square of the standard deviation.

`\text{Variance} = (\text{Standard Deviation})^2\\= (5.8\text{ pounds})^2\\=33.64\text{ pound}^2`

Thus, the variance of given sample is 33.64 square pounds.
