In a study of the accuracy of fast food drive-through orders, one restaurant had 39 orders that were not accurate amo 328 orders observed. Use a 0.05 significance level to test the claim that the rate of inaccurate orders is equal to 10% Does the accuracy rate appear to be accentable?

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.
