Question

A random sample of 10 subjects have weights with a standard deviation of 11.9407 kg. What is the variance of their​ weights? Be sure to include the appropriate units with the result. The variance of the sample data is nothing ▼ kg cubed . kg squared . kg. ​(Round to four decimal places as​ needed.)

    Answer: 142.58\text{squared kg}[

    Step-by-step explanation:

    Answer:

    Step-by-step explanation:

    Given : A random sample of 10 subjects have weights with a standard deviation of 11.9407 kg

    i.e. \sigma = 11.9407

    Since we know that the value of variance is the square of standard deviation.

    i.e. \text{Variance}=\sigma^2

    Therefore, to find the value of variance, we need to find the square of the given standard deviation.

    i.e. \text{Variance}=(11.9407)^2=142.58031649\approx142.58\text{squared kg}

    Thus, the variance of their​ weights =142.58\text{squared kg}[
