A researcher uses a sample of n = 25 individuals to evaluate the effect of a treatment. The hypothesis test uses a = .05 and produces a significant result with t = 2.15. How would the statistical sentence be reported? a. t(25) = 2.15, p < .05 b. t(24) = 2.15, p < .05 c. t(25) = 2.15, p > .05 (incorrect answer) d. t(24) = 2.15, p > .05

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
