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.
An environmentalist is interested in the opinions of adults on the issue of global warming. In particular, he wants to estimate the proportion of people who think that global warming is a very serious problem. In a random sample of n = 100 adults, 73% indicated that global warming is a very serious problem. Estimate the true proportion of the adult population who think global warming is a very serious problem and find the margin of error for the estimate. Use 95% CI.
