The typical (rule of thumb) alpha level used in hypothesis testing is usually 0.05, which means there is a 5% chance of making a Type I error (rejecting a true null hypothesis). While other alpha levels like 0.02 and 0.10 can be used depending on the situation, 0.05 is the most commonly used and generally accepted level.
