Dit resultaat toont aan dat de mannelijke studenten een intrinsieke motivatie - to know hebben van 20. Dit omdat 20 deel uitmaakt van het interval [19.5619876187585, 21.0094409526700]. Dus we accepteren de nulhypothese. De mannelijke I1 score is niet significant verschillen van 10 bij een 5% type I error level.
