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.
At Phoenix Sky Harbor International Airport, 83% of recent flights have arrived on time. Suppose 20 flights are randomly selected.
- What is the
probability that at least 17 of the flights arrived on time?
So I already had this question answered on this site, but I didn't understand what the person was doing. Is this binomcdf or binompdf? Which ones are the n, p, and x? Do I need to do 1-(17,.83, 20)?
or is this μx=np? Please help by better explaining this.
