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.

Poisson model in traffic safety • Here we make the assumption of a Poisson process. (What does that imply?) • For a Poisson process, the probability of seeing exactly x events in a time interval t is P(x)=where l is the average rate of occurrence. Suppose the crash reports show a trend of 25 crashes/year. At a 95% odds, what is the highest number of accidents we would see in a month? if a graph was used please attach below and explain

Solve this question using Rstudio. Some previous studies have shown a relationship between emergency-room admissions per day and level of pollution on a given day. A small local hospital finds that the number of admissions to the emergency ward on a single day ordinarily (unless there is unusually high pollution) follows a Poisson distribution with mean = 2.0 admissions per day. Suppose each admitted person to the emergency ward stays there for exactly 1 day and is then discharged. The hospital is planning a new emergency-room facility. It wants enough beds in the emergency ward so that for at least 95% of normal-pollution days it will not need to turn anyone away. What is the smallest number of beds it should have to satisfy this criterion?
Discrete distributions A GIS firm is investigating the safety of a dangerous road stretch in the Himalayas. Historical data indicates an average of 6 landslides per year over this stretch. The number of landslides is distributed according to a Poisson distribution. The firm wants to calculate the probability of exactly 3 landslides in any year
A crew of mechanics at the Department of Transportation garage make minor repairs to snowplows during the winter. The snowplows break down at an average rate of 4 vehicles per day and breakdowns are distributed according to the Poisson distribution. The mechanic can service an average of 7 vehicles per day with a repair time distribution that approximates a negative exponential distribution. Assume an 8 hour day. On average, how long does a plow wait before the mechanic begins the repair?
