A local bank has two branches in a city: one in the business center of the city and another-in aresidential area. The bank's operations manager wants to Improve front-office employee scheduling during the lunch hour (12:00-13:00) period. The manager starts with studying the customer waiting times at the two branches and collects data for two groups of 35 customers at each branch. Customers at the business-center branch waited on average 38 minutes, whle those at the residential branch waited 44 minutes on average. Assume that the population standard deviations are 1.8 (businesscenter branch) and 2.5 tresidential branch. a. Considering the real-de problem, determine the point estimate of the unknown quantity that needs to be estimated (Round to two decimal places) b. Determine the critical value needed to compute a Ba confidence interval (Round to two decimal places)

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.
