A political candidate is recruiting volunteers to help with their campaign. On their website they are testing to see if a button that says “Learn More” gets more responses than a button that says “Sign Up” They run both versions of the website for 30 days in a way that users are randomly assigned to a version of the website. After the trial period of the 7845 visitors who visited the “Learn More” version 689 people clicked the button, and of the 7861 people who visited the “Sign Up” version 513 clicked the button. Consider the necessary assumptions for a Z test for difference in proportions. Choose the best answer.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
