You have two samples. Sample 1 has 200 African American people and Sample 2 has 300 Hispanic people. Sample 1 has 104 individuals with type O and Sample 2 has 180 individuals with type O. 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 Critical -score 90% 5% 1.645 95% 2.5% 1.96 99% 0.5% 2.576 The calculated -score is 1.77, which is not less than the critical value of 1.96, so we fail to reject the null hypothesis. The calculated -score is 1.77, which is not less than the critical value of 1.96, so we reject the null hypothesis. The calculated -score is 1.77, which is not greater than the critical value of 1.96, so we fail to reject the null hypothesis. The calculated -score is 1.77, which is not greater than the critical value of 1.96, so we reject the null hypothesis
