ALL PARTS A,B,C Over the past 5 years, U.S. airlines average about 1 fatality per month (U.S. Department of Transportation, National Transportation Statistics: 2015). Assume that the probability distribution for x, the number of fatalities per month, can be approximated by a Poisson probability distribution. (a) What is the probability that no fatalities will occur during any given month? (b) What is the probability that one fatality will occur during a month?(c) Find E(x) and the standard deviation of x.
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.
