When constructing a confidence interval for a population parameter, we generally set the confidence coefficient ( ) close to 0 (usually between 0 and 0.05) because it is the probability that the interval does not include the actual value of the population parameter.

When constructing a confidence interval, we generally set the confidence level (not the confidence coefficient) close to 1 (usually between 0.90 and 0.99), because it represents the probability that the interval includes the actual value of the population parameter. The confidence coefficient is simply 1 minus the confidence level.
