Each year ratings are compiled concerning the performance of new cars during the first 90 days of use. Suppose that the cars have been categorized according to whether a car needs a warranty-related (yes or no) and the country in the company manufacturing a car is based (United States or not United states). Based on the data collected, the probability that the new car needs a warranty repair and was manufactured by a U.S based company is 0.025. Construct a contingency table to evaluate the probabilities. What is the probability that a respondent chosen at random a. needs a warranty repair? b. needs a warranty repair and was manufactured by a U.S.-based company? c. needs a warranty repair or was manufactured by a U.S.-based company? d. needs a warranty repair or was not manufactured by a U.S.-based company?
