p^1 = x1/n1

p^2 = x2/n2

q^1 = 1 - p^1

q^2 = 1 - p^2

(p^{^}1 - p^{^}2) - z_{α/2}*I < p_{1} - p_{2} < (p^{^}1 - p^{^}2) + z_{α/2}*I

- alternative hypothesis
- opposite of null hypothesis. One of the proposed proposition in the hypothesis test.

H_{1} - confidence interval
- a range of values so defined that there is a specified probability that the value of a parameter lies within it.
- difference of proportions test
- hypothesis
- statistical test using a statement of a possible explanation for some conclusions
- null hypothesis
- in a statistical test, the hypothesis that there is no significant difference between specified populations, any observed difference being due to sampling or experimental error.

H_{0} - proportion
- n equation in which two ratios are set equal to each other

a/b = c/d - test statistic
- a number calculated by a statistical test
