From past experience a television manufacturer found that 15% or less of its sets needed any type of repair in the first two years of operation. In a sample of 60 sets manufactured two years ago, 10 needed a repair. Test the original claim at 3% SL. Apply one-sided test, give a complete calculation. Finally interpret the conclusion in terms of the example.
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.
