Final answer:
The answer is Yes, there is evidence that the weight is different from 368 grams.
Step-by-step explanation:
The question is asking whether there is evidence that the weight is different from 368 grams. To determine this, we need to consider the concept of the just-noticeable difference. The just-noticeable difference refers to the smallest change in weight that can be detected by a person. According to the information provided, a difference between 1 and 2 units of weight is more likely detectable than a difference between 20 and 21 units. Therefore, based on this information, the answer is Yes, there is evidence that the weight is different from 368 grams.
