A book is randomly chosen from a library shelf. For each of the following characteristics of the book, decide whether the characteristic is a continuous or a discrete random variable. (a) Weight of the book (e.g., 2.6 pounds). continuousdiscrete (b) Number of chapters in the book (e.g., 9 chapters). continuousdiscrete (c) Width of the book (e.g., 9 inches). continuousdiscrete (d) Type of book (0 = hardback or 1 = paperback). continuousdiscrete (e) Number of typographical errors in the book (e.g., 3 errors). continuousdiscrete
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.
