Is this sentence correct ?

Question

If you decrease the risk of a type I error, the risk of a type II error is increased

Answer 1

A Type I error is a false positive, i.e. I think this is true, but it is really false. A Type II error is a false negative i.e. I think this is false, but it is really true. The chances of committing these two kinds of errors is inversely proportional thus, your sentence is correct. When you decrease type 1 error risk you necessarily increase type 2 error risk and vice versa.
