Louis Armstrong, salesman for the Dillard Paper Company, has five accounts to visit per day. It is suggested that the variable, sales by Mr. Armstrong, may be described by the binomial distribution, with the probability of selling each accounts being 0.4. Given the following frequency distribution of Armstrong’s number of sales per day, can we conclude that the data do in fact follow the suggested distribution? Use the 0.05 significance level. Number of sales per day 0 1 2 3 4 5 Frequency 10 41 60 20 6 3

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.
