[@samh6814]

So I defined the significance level as “the limit before you decide against the null hypothesis” would this be correct?

[@TLMaths]

It's not particularly formal to refer to a limit here. The significance level is defined as 'the probability of rejecting the null hypothesis when in fact it is true'. It is effectively defined in a practical way, referring to the chance of you making a mistake (i.e. incorrectly rejecting the null hypothesis).

Hi I need help can you tell us an example where using a smaller significance level is preferred when carrying out hypothesis testing

[@TLMaths]

This is a very good read on this subject and it gives examples of changing the significance level: statisticsbyjim.com/hypothesis-testing/significance-levels/
