A television station sells advertising in 15-, 30-, 60-, 90- and 120-minute blocks. The distribution of sales for one 24-hour day is: 1. Length in seconds 15 30 60 90 120 Probability 0.134 0.786 0.053 0.006 0.023 Find the mean, variance and standard deviation of the probability distribution.
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.
