A researcher is interested in determining if the proportion of children that collect specific types of toys is equal. To test, he takes a random sample of 500 children and finds that 36% of them collect Legos, 19% of them collect Beenie Babies, 18% of them collect Webkinz, and 27% of them collect Hot Wheels. At the 10% significance level, what conclusion can be reached?

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.
