Concept explainers

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.

Many fire stations handle emergency calls for medical assistance as well as calls requesting firefighting equipment. A particular station says that the probability that an incoming call is for medical assistance is 0.84. This can be expressed as P(call is for medical assistance) = 0.84. (a) Give a relative frequency interpretation of the given probability. O Eighty-four percent of all calls to the station are for medical assistance. O None of the calls to the station are for medical assistance. O Sixteen percent of all calls to the station are for medical assistance. O All calls to the station are for medical assistance. O Fifty percent of all calls to the station are for medical assistance. (b) What is the probability that a call is not for medical assistance?

Your friend Phil, asks you what you think about a new scratch-off lottery game. It costs $10 to play this game, There are two outcomes for the game (win, lose) and the probability that a player wins a game is 60%.
