A b means that a is less than or the same as b. 2 probability the chance of a certain event happening. Web confidence level = 1 − a so if you use an alpha value of p < 0.05 for statistical significance, then your confidence level would be 1 − 0.05 = 0.95, or 95%.

When do you use confidence intervals? Web confidence level = 1 − a so if you use an alpha value of p < 0.05 for statistical significance, then your confidence level would be 1 − 0.05 = 0.95, or 95%.
