Final answer:
This situation illustrates how it's often difficult to distinguish the sender from the receiver of a message, making communication a better term for these roles.
Step-by-step explanation:
The situation described in the question illustrates how it can be difficult to distinguish between the sender and receiver of a message, making 'communication' a better term for these roles. In this case, the math professor is sending information about a difficult statistical problem, but the students are having trouble receiving and understanding the message.
Communication involves both sending and receiving messages, and when there is confusion or a lack of understanding, effective communication is compromised. In this context, the sender is the math professor who is trying to explain the problem, and the receivers are the students who are trying to comprehend the information.
Improving communication between the math professor and the students can help reduce confusion and improve understanding of the statistical problem at hand. So therefore the situation described in the question illustrates how it can be difficult to distinguish between the sender and receiver of a message, making communication a better term for these roles.
