Two weights, each labeled as weighing 100 g, are each weighed several times on the same scale. The results, in units of μg above 100 g, are as follows:

Since the same scale was used for both weights, and since both weights are similar, it is reasonable to assume that the variance of the weighing does not depend on the object being weighed. Can you conclude that the weights differ?
