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

9.) Is there a relationship between gender and relative finger length? To find out, we
randomly selected 452 U.S. high school students who completed a survey. The two-way
table summarizes the relationship between gender and which finger was longer on the
left hand (index finger or ring finger).
Gender

Suppose we randomly select one of the survey respondents. Define events R: ring finger
longer and F: female.
a.) Find P(R|F).
b.) Given that the chosen student does not have a longer ring finger, what's the
probability that this person is male? Write your answer as a probability statement
using correct symbols for the events.
