How are type 1 and type 2 errors related

The Type I and Type II error rates influence each other. That’s because the significance level (the Type I error rate) affectsstatistical power, which is inversely related to the Type II error rate. This means there’s an important tradeoff between Type I and Type II errors: 1.
