Consider a sample of 100 people and subsequently a confidence interval calculated from the sample. How will the interval change if the sample of people is reduced to 50? It will become narrower. It will become wider. "It will remain the same, because the mean is not changing." It will get closer to 1.96. None of the above.
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.
