    • ‘Even though this is the widest possible confidence interval, it achieves a confidence level of only 65%.’
    • ‘The size of this range will depend upon the data set, as well as the chosen confidence level of the statistical test.’
    • ‘To calculate the confidence level associated with any such interval, we use binomial probabilities in the same manner as described earlier.’
    • ‘If the probability is higher than a given confidence level, positive selection is inferred.’
