A hоspitаl infectiоn cоntrol officer investigаtes whether hаnd-hygiene compliance rates differ between the intensive care unit (ICU) and the general medical ward (GMW). Group 1 (ICU): n1=120, f1=85, p^1=0.7083. Group 2 (GMW): n2=85, f2=50, p^2=0.5882. A two-tailed two-sample proportions z-test at α=0.10 returns pooled proportion p^=0.6585, standard error =0.067226, test statistic z=1.7865, p-value =0.0740, critical value zcv=1.6452, and CI90=(0.009497,0.230699). Which of the following correctly identifies the statistical decision, the correct comparison that supports it, and the proper interpretation of the confidence interval result?
