The significance level, often denoted as α (alpha), is the probability of rejecting the null hypothesis when it is true. It is typically set before conducting the hypothesis test.
In this case, we are not conducting a hypothesis test, but rather calculating a confidence interval. The confidence level is 90%, which is equivalent to a significance level of α = 1 - confidence level = 0.1 (or 10%).
