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.
The Center for Information Technology at State Univer-
sity has outgrown its office in Bates (B) Hall and is mov-
ing to Allen (A) Hall, which has more space. The move
will take place during the three-week break between the
end of summer semester and the beginning of fall semes-
ter. Movers will be hired from the university’s physical
plant to move the furniture, boxes of books, and files that
the faculty will pack. The center has hired a local retail
computer firm to move its office computers so they will
not be damaged. Following is a list of activities, their
precedence relationships, and probabilistic time estimates
for this project:Determine the earliest and latest start and finish times, the
critical path, and the expected project duration. What is the
probability the center will complete its move before the
start of the fall semester?
