With another study, where you also plan on evaluating a mean using the t statistic, you have a sample of n = 21 that has an ss of 500. what is the variance for the sample? 22. 36 250,000 25 5. 0

Sagot :

The variance for the sample is 25

For given question,

We have been given the sample size n = 21

and the sum of squares is SS = 500

We need to find the variance for the sample.

We know that the variance is mathematically represented as,

[tex]\sigma^2=\frac{SS}{n-1}[/tex]

Substituting given values in the above formula,

[tex]\Rightarrow \sigma^2\\\\=\frac{500}{21-1}[/tex]

= 500 / 20

= 25

So, the variance is 25

Therefore, the variance for the sample is 25
