The test statistics which will be used here is standard deviation.
<h3>What is standard deviation?</h3>
The standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance. The standard deviation is calculated as the square root of variance by determining each data point's deviation relative to the mean.
A volatile stock has a high standard deviation, while the deviation of a stable blue-chip stock is usually rather low.
Thus, Option D is true, as standard deviation is the test statistics which will be used here.
