What is the p-value? (using three decimal places) What is the conclusion? What type of error is at risk
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.

A plan for an executive travelers’ club has been developed by an airline on the premise that 5% of its current customers would qualify for membership. A random sample of 500 customers yielded 40 who would qualify. Is there significant evidence to show that the proportion of customers from the sample who would qualify for membership is larger than 5%(the current proportion). What is the p-value? (using three decimal places) What is the conclusion? What type of error is at risk? |
