Yes.

#### Explanation:

Type I error and Type 2 error have an inverse relationship. If probability of one error is decreased, the other one will increase. Typically, we cannot simultaneously reduce type I and Type II error.

But there is one way to reduce both simultaneously, i.e, by increasing sample size.
