Q:

Converting a table to an ORM schema

I'm trying to convert this table into an ORM schema: 
The solution given by the book is this one: 
It connects all the paramether to the Member one. This is my solution, which I think it's less complicated, but I don't know if it is equivalent: 
What do you think about my solution? Is it right?

A:

Conceptually, I'd say that it is wrong, since a person's heart rate does not have a reaction time. Similarly, a sport such as tennis does not make a booking, a member makes a booking.
