A factory plant is studying the number of accidents per month. The table below gives the distribution of the number of accidents per month. 0. 1 3 4 p(x) 0.715 0.130 0.072 0.060 0.021 0.002
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.
What is the probability that 3 or more accidents will occur next month?
Find the probability that at most 2 accidents will occur next month.
Find the expected number of accidents per month.
Find the standard deviation of the number of accidents per month.
When accidents occur, the plant must stop and there is a delay in the production of 3 hours. Find the expected number of delay hours due to accidents each month.
What is the standard deviation of delay hours due to accidents each month?
