According to the national Center for health statistics, 74% of American women have been married by the age of 30. Suppose in a survey of 125 American women ( who are at least 30) and it is found that 91 of them were married at least once. Does the survey provide significant evidence that less than 74% of American women have been married by the age of 30? Test the relevant hypotheses at a significance level of 0.10.
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.
