In hypothesis testing, why are verbal problem statements converted to numerical problem statements?
Why is it important to identify the parameter when converting a problem statement from verbal to numerical?
Why do a null and alternative hypothesis have to be mutually exclusive?

If I have read your questions correctly:
1. To attempt to solve the problem.
2. What units are you talking about? Pounds? Meters? Decibels?
3. How can something be true and not true at the same time?
I hope this helps.
