44. US Airlines receives an average of 500 calls per hourfrom customers who want to make reservations, wherethe times between calls follow an exponential distribution. It takes an average of three minutes to handleeach call. Each customer who buys a ticket contributes$100 to US Airlines profit. It costs $15 per hour tostaff a telephone line. Any customer who receives abusy signal will purchase a ticket from another airline. How many telephone lines should US Airlineshave? Base your answer on an appropriate simulation.Does it matter whether the service times are exponentially distributed or gamma distributed? Experimentto find out.
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.
