Over the course of a year, a family measures how many hours of TV they watch each day. Probability of watching certain amounts of TV each day Hours Probability 3= .1 4= .3 5= .4 6= .1 7= .1 On any given day, what is the expected number of hours they will watch? (Provide your answer to 2 decimal places.) What is the variance for the number of hours they watch?
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.
