You randomly selected 50 individuals twice. In the first sample, 15 of the 50 had blue eyes. In the second sample, 25 of the 50 had blue eyes. Find the calculated -score used to compare proportions and interpret it. Use a confidence level of 95%. For your convenience, the formula is

Confidence Level a/2 Critical -score
90% 5% 1.645
95% 2.5% 1.96
99% 0.5% 2.576
