Can you help me answer these statistics true and false questions?

1) When we reject or do not reject the null hypothesis the level of significance tells us how confident we are in making the correct decision.


2) A one tail test points out the null hypothesis should be rejected when the test statistic value is in the critical region.


3) The level of significance can be any value between 0 and 1 inclusive.





Please answer these and let me know why they are true or false. Thank youCan you help me answer these statistics true and false questions?
1) is false, since, for example, a failure to reject when we should not have is related to type II error rate, not type I.





2) well, yes, but so does a two-tail test!





3) sure, you could do that but 0 and 1 (always reject, always accept) are useless
