Table 4 summarizes the results of this hypothesis test. As shown in this table, it was confirmed that the ratio data (
) between the concentration time and the storage coefficient could be assumed constant in all basins. In all basins considered in this study, the p-value was estimated to be far larger than 0.05; as a result, the null hypothesis could not be rejected.
