True–False Exams. If, in Example 6.20, the true–false exam had 30 questions instead of 10, which normal curve would you use to approximate probabilities for the number of correct guesses? attending colleges and universities, and women in particular, are at higher risk of being victims of sexual assault than are their non–college-bound peers. According to research, 13% of college women have been stalked. If 100 college women are selected at random, what is the probability that the number who have been stalked is a. less than 10? b. between 15 and 20, inclusive? c. at least 15?
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.
