NOTE: n represents the actual unweighted sample size in each group. Estimates were obtained using C-SIDE v1.0 (C-SIDE courtesy of Iowa State University Statistical Laboratory). Standard errors (SE) were estimated via jackknife replication. Each standard error has 43 d.f. ^a These estimates are less reliable due to extremely small sample size.
