    1. The 3 ways to test a hypothesis is by finding the critical value, finding a p-value or finidng a cofidence interval. Is that what is meant by the question?

    2. 1-\alpha

    3. Construct an interval and you will see it is the middle.

    4. When \sigma is unknown

    5. I think you need more information to determine the null and alternate hypothesis here.
