    Level of significance is the preset probability of committing a type I error, that is to reject a null hypothesis when it is true.

    1.

    If a larger significance level is used, type I error is more likely to be made.

    2.

    If a smaller significance level is used, it is harder for you to reject a null hypothesis, then even if the null hypothesis is false, it is hard to reject it, so it is more likely to commit a type II error, which is not to reject the null hypothesis when it is false.
