A school district compared the proportion of students who pass a math proficiency exam in two independent random samples: 44 of 80 students from School X passed and 70 of 140 students from School Y passed. A two-proportion zz test was conducted at α=0.05\alpha=0.05 to test H0:pX=pYH_0: p_X=p_Y versus Ha:pX>pYH_a: p_X>p_Y, where pXp_X and pYp_Y are the true passing proportions at Schools X and Y. The p-value was 0.12. What conclusion is appropriate?
