You flip a coin 8 times and record the results using 0 for heads and 1 for tails. You find the variance. Is investigating this sample variance the same as investigating the sampling distribution of the variance?

C. No, the sampling distribution of the variance is the distribution of the means from all samples, not just one.
D. Yes, the probability of getting heads and the probability of getting tails is the same
