Amusement Ride Safety. Approximately 297 million guests visit the 400 American amusement parks annually and take 1.7 billion safe rides. The National Safety Council publishes a report titled Fixed-Site Amusement Ride Injury Survey for the International Association of Amusement Parks and Attractions. The number of injuries per million patron-rides, X, has a Poisson distribution with parameter 0.8. In one million patron-rides, what is the probability that there are a. no injuries? b. more than two injuries? c. Construct a table of probabilities for the random variable X. Computethe probabilities until they are zero to three decimal places. d. Draw a histogram of the probabilities in part (c).
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.
