frq styled response a company rents DVDs from vending machines in grocery stores has developed the following probability distribution for the random variable x=the number of DVDs a randomly selected customer rents from the machines a find and interpret the mean of x b find and interpret and standard deviation of x c suppose the profit the company makes on each customers visit is $0.75 per DVD minus $0.05 "fixed costs"that is, if P= profit, then P=0.75x-0.05. find the mean and stardard devation of P.
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.
