kidly answert both parts A researcher is interested in evaluating the earnings of airport staff in the United States (US). Suppose the US has about 5,200 airports. A decision is made to classify all 5,200 airports as distinct groups, where the employees of each airport represent a group. You then perform simple random sampling technique to select 100 airports from your 5,200 groups. The earnings of the employees in those 100 airports will represent the primary data for your study. a) Did you perfom stratified random sampling or cluster sampling? Explain. b) What advantage might it have other simple random sampling?
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.
