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.

Question

In a survey of consumers aged 12 and older, respondents were asked how many cell phones were in use by the household. (No two respondents were from the same household.) Among the respondents, 203 answered "none," 294 said "one,"
364 said "two," 143 said "three," and 139 responded with four or more. A survey respondent is selected at random. Find the probability that his/her household has four or more cell phones in use. Is it unlikely for a household to have four or more
cell phones in use? Consider an event to be unlikely if its probability is less than or equal to 0.05.
P(four or more cell phones) =
%3D
(Round to three decimal places as needed.)
Is it unlikely for a household to have four or more cell phones in use?
A. Yes, because the probability of a respondent with four or more cell phones in use is less than or equal to 0.05.
B. Yes, because the probability of a respondent with four or more cell phones in use is greater than 0.05.
C. No, because the probability of a respondent with four or more cell phones in use is greater than 0.05.
D. No, because the probability of a respondent with four or more cell phones in use is less than or equal to 0.05.
