In a given year, 13.5% of working people in the US claim to be a member of a union. A research team was hired to randomly contact 2000 city workers and 240 claims union membership. Is there a sufficient evidence to cook conclude that the proportion of workers in this large city (population 500,000) who are union members is different from the national right? (Use a significance level of 0.05 (Alpha) Question : what is the p value ? what is your conclusion ?
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.
