The arrival of flights at DIA has been monitored for the last year. From the research, 32% of all arrivals are on time. Suppose a random sample of 10 flight arrivals is examined. Using the binomial functions, give the probability: (a) Of exactly 4 on time arrivals. (b) Of at most 6 on time arrivals? (c) Give the expected(mean) number on time arrivals.
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.
