Answer:
And if we take the average value of the sample variances from all the possible random samples we will get the population variance:
So then the best answer for this case would be:
The average value of the sample variances from all the possible random samples will be exactly the population variance
Step-by-step explanation:
For this case we can define the sum of squares with this formula:
Where:
And we can find the sample variance with this formula:
And if we take the average value of the sample variances from all the possible random samples we will get the population variance:
So then the best answer for this case would be:
The average value of the sample variances from all the possible random samples will be exactly the population variance
