You are conducting a study to see if the proportion of voters who prefer Candidate A is significantly more than 0.67. Thus, you are performing a right-tailed test. Your sample data produce the test statistic z = 2.753. Find the p-value accurate to 4 decimal places. NOTE: Since you are given the z-score, use the NORMAL DISTRIBUTION calculator with μ=0 and σ=1. p-value = P(z > 2.753) =
