WebTo avoid “false positive” mistakes, we need to set the confidence level, also known as “statistical significance.” This number should be a small positive number often set to 0.05, which means that given a valid model, there is only a 5% chance of making a type I mistake. WebIt turns out that if the sum of your confidence level and your significance level is equal to 100% and you're doing a two-sided hypothesis test, so you're thinking about well, our alternative hypothesis isn't just that the in-person is greater than the online, or that it's less than the online, it's that they are different.
