Complete parts (a) and (b) below. The number of dogs per household in a small town Dogs 0 1 2 3 4 5 Probability 0.676 0.206 0.080 0.021 0.012 0.005 (a) Find the mean, variance, and standard deviation of the probability distribution. Find the mean of the probability distribution. μ=??? (Round to one decimal place as needed.) (b) Use the found values of the mean and the standard deviation to interpret the results in the context of the real-life situation.
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.
