You have seen that hypothesis test are run at different levels. Sometimes the level is .1 which gives you 90% confidence. Other times the level is .01 which gives you 99% confidence. In this post comment on the following three items.

1. What would be the benefits to using a .1 level? Give an example of where you feel this might be the most appropriate level. Explain why you think it would be a good level to use.

2. What would be the benefits to using a .01 level? Give an example of where you feel this might be the most appropriate level. Explain why you think it would be a good level to use.

3. Most tests are done at a .05 level. Why do you think that is the case?
