#3 In a study of the accuracy of fast food drive-through orders, one restaurant had 30 orders that were not accurate among 371 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 acceptable? Identify the test statistic for this hypothesis test. The P-value for this hypothesis test Then, use this information to state a final conclusion that addresses the original claim with wording that can be understood by those without knowledge of statistical procedures. Use the conclusion from the previous step to think about whether or not the accuracy rate is acceptable.
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.
