In a general case, suppose if I take (alpha/2) = 2.5% and my null hypothesis is rejected in the solution done by me. While, the solution has (alpha/2) =5%, and is showing that H0 is accepted , so will my solution be held valid if I state correctly my assumption and my answer? Hoping for an early response. Thank you Shyam
If the question states alpha level of significance then use that level. Otherwise 95% l.o.s is accepted generally.
Depends on the question wordings. So if asked to test for say alpha % of significanse level then it should be alpha. And have not specified alpha then 5%
