Quizplus · Accepted Answer

The sample variance is calculated using the formula for variance, which involves summing the squared differences between each data point and the mean, then dividing by the number of data points minus one (for sample variance). The correct calculation based on the provided data (not shown here) results in 404.49, indicating option A is correct.
