A study was done in a large undergraduate classroom asking the students to record how many hours they spent doing homework on a typical day rounded to the nearest hour. The data was organized by recording the number of hours (X) and the number of students who responded with that number of hours (frequency). X (# of hours) Frequency of X=x x = 0 7 x = 1 7 x = 2 13 x = 3 4 x = 4 2 Based on these findings, what is the expected number of hours than a student selected at random from this classroom would spend studying each day?
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.
