Note: ** denotes null rejected at 1% level; * null rejected at 5% level. Source: calculations based on weighted FAME

^a In each instance we are testing the two sub-groups listed against each other, with the null that the distribution of one sub-group dominates the other; the values measure the
greatest difference between the two sub-groups, and a positive value means that a sub-group lies to the left of the opposing sub-group.
