Leakage from underground gasoline tanks at service stations can damage the environment. It is estimated that 30% of these tanks leak. You randomly choose 30 tanks at random. a. Does the binomial setting apply? Explain b. What is the mean number of leaking tanks in such samples of 30 tanks? What is the standard deviation? c. What is the probability that exactly 25 of these tanks leak? d. What is the probability that at most 15 tanks leak in samples of 30 tanks?
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.
