There is insufficient evidence to reject the proportion of men who own cats is 25% with .005 significance level. There is insufficient evidence that the proportion of men who own cats is larger than 25% with .005 significance level. The proportion of men who own cats is larger than 25% with .005 significance level. The proportion of men who own cats is 25% with .005 significance level. The proportion of men who own cats is not 25% with .005 significance level.

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.
