Customer service time is modeled as an exponential random variable with mean 5 minutes. Find the probability that service for a customer is between 2 minutes and 10 minutes. Round your answer to the nearest hundredth. Before you answer the question, what is the parameter for the exponential distribution. (Hint: the parameter is not 5!).
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.
