For an assignment tomorrow, I need to test a hypothesis about the equality of two population means. The null hypothesis states that the means are equal. while the alternative states that they're different. The sample size (n) is 200 and the level of significance is 0.02. How would I calculate; The appropriate testing statistic and sampling distribution The critical values that seperate the rejection and nonrejection region

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.

Question

The appropriate testing statistic and sampling distribution
The critical values that seperate the rejection and nonrejection region

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
