Suppose, out of the next 20 customers, the count that will pay with a credit card (X) has a Binomial distribution with parameters n = 20 and p = 0.70. Use the Binomial Excel Spreadsheet to answer: What is the probability that strictly between 11 and 14 customers pay by credit card. P( 11 < X < 14) = Round to 4 decimal places.
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.
