At a certain college, it is estimated that at most 35% of the students ride bicycles to class. At what level of significance this seem to be a valid estimate if, in a random sample of 90 college students, 28 are found to ride bicycles to class?
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.
