Each year, ratings are compiled concerning the performance of new cars during the first 30 days of use. Suppose that the cars have been categorized according to whether a car needs warranty-related repair (yes or no) and the country in which the company manufacturing a car is based (in some country X or not in country X). Based on the data collected, the probability that the new car needs a warranty repair is 0.08, the probability that the car is manufactured by a company based in country X is 0.50,and the probability that the new car needs a warranty repair and was manufactured by a company based in country X is 0.015. Show contingency table used. a. Suppose you know that a company based in country X manufactured a particular car. What is the probability that the car needs warranty repair?
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.
