    The confidence interval is the interval provides a range of plausible values for the proportion of all jobs applicants who test positive when they are tested for drug use. We are 95% confident about the interval (0.0262, 0.0499) in the sense that 95% of the intervals calculated in this way will contain the proportion of all jobs applicants who test positive when they are tested for drug use.
