If we try to decrease the probability of a Type I error occuring, we increase the probability of a Type II error occuring, resulting in a tradeoff.

     "The conventional significance levels are $0.1$, $0.05$, and $0.01$. Rejecting the null at $0.1$ mean that we have some evidence null is false, $0.05$ means we have strong evidence null is false, rejecting at $0.01$ we have very strong evidence that null is false."
