A finance company records a large amount information. Normally, there are 1.5 errors per 100 files. Let ? be the random variable representing the number of errors in 100 files. i. If ? has a Poisson distribution, write down the value/s of its parameter/s. ii. What is the probability that there are three errors in a randomly selected 100 pages? iii. What is the probability that there are three or more errors in a randomly selected
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.
