If you increase alpha, you both increase the probability of incorrectly rejecting the null hypothesis and also decrease your confidence level. Fact 2: If the p-value is low, the null must go. The confidence level or also known as the confidence level or risk level is based on the idea that comes from the Central Limit Theorem. The level of confidence is denoted by 100 (1 – α)% as the main idea that comes from the theorem is that if a population is repeatedly drawn the sample, then the average attribute value obtained from these samples is parallel to the actual population value.
