5. In Example 11.2, the gamma distribution was usedto model the skewness to the right of the lifetimedistribution. Experiment to see whether the triangulardistribution could have been used instead. Let itsminimum value be 0, and choose its most likely andmaximum values so that this triangular distributionhas approximately the same mean and standarddeviation as the gamma distribution in theexample. (Use @RISK’s Define Distributionswindow and trial and error to do this.) Then runthe simulation and comment on similarities ordifferences between your outputs and the outputs inthe example
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.
