This is a correct statement as there is an inverse relationship between ARIA and sample size. As ARIA increases, the probability of accepting a lot that should be rejected increases, which means that sample size will need to be increased to reduce this risk. Thus, as ARIA decreases, sample size will need to be increased to maintain the same level of confidence in the acceptance decision. Therefore, as ARIA increases, sample size decreases.
