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.

5.34 An appliance manufacturer offers extended war-
ranties on its washers and dryers. Based on past sales,
the manufacturer reports that of customers buying both
a washer and a dryer, 52% purchase the extended war-
ranty for the washer, 47% purchase the extended warranty
for the dryer, and 59% purchase at least one of the two
extended warranties.
a. Use the given probability information to set up a hypo-
thetical 1000 table.
b. Use the table from Part (a) to find the following
probabilities:
i. the probability that a randomly selected cus-
tomer who buys a washer and a dryer purchases
an extended warranty for both the washer and the
dryer.
ii. the probability that a randomly selected customer
purchases an extended warranty for neither the washer
nor the dryer.
