Selene’s immediate superior notices that she tends to commit an average of 15 errors for every 50 pages of her report. If 20 pages are selected at random and Poisson distribution applies, what is the probability that: A. more than 6 errors are found? B. a maximum of 11 errors is found? C. at most 8 errors are found?
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.
