After constant complaints about the long wait from his customers, Ryan - the owner of shop - has decided to hire a second mechanic to handle installations. Customers, who arrive at a rate of about 3 per hour (Poisson), will wait in a single line until one of the two mechanics is free. Each mechanic can serve about four customers per hour (Exponential). Do you think the improvement on customer experience will be significant? Compute the key waiting line characteristics BEFORE and AFTER the second mechanic is hired to support your answer.
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.
