She concludes that her hypothesis was correct and decides to always play music for her clients. What was the trainer's hypothesis? Music does not motivate her clients to train more O O Music makes the weights feel lighter Music makes her clients weaker Music makes her clients stronger Music makes the weights feel heavier Music motivates her clients to train more
