A wildlife ecоlоgist is testing whether the prоportion of juvenile Atlаntic sаlmon exhibiting аggressive territorial behavior differs between two geographically distinct river populations. Independent random samples yield: Group 1 (northern river), n1=340 juveniles observed, f1=120 displaying the behavior (p^1=0.3529); Group 2 (southern river), n2=330 juveniles observed, f2=110 displaying the behavior (p^2=0.3333). A two-tailed two-sample independent proportions z-test is conducted with H0:P1−P2=0 and Ha:P1−P2≠0 at α=0.05. The calculator returns pooled proportion p^=0.3433, standard error =0.036691, test statistic z=0.5344, p-value =0.5931, critical value zcv=1.9604, and CI95=(−0.052320,0.091536). Which of the following completely and correctly explains both the statistical decision AND the conclusion that properly follows from examining the confidence interval?
