Calculating the degrees of freedom, the sample variance, and the estimated standard error for evaluations. using the t statistic.

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?

A. 5.00

B. 22. 36

C. 25

D. 250,000

The variance is  

Step-by-step explanation:

From the question we are told that

    The sample size is  n =  21

     The sum of squares is

Generally the variance is mathematically represented as

substituting values

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
