a.) The Mean amount of Americans who own a smartphone. b.) Using a Binomial Distribution, find the probability that 170 Americans will own a smartphone. c.) Now, using the Poisson Distribution, find the probability that 170 Americans will own a smartphone. d.) Which do you feel is a better estimate? Why?
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.
Read each prompt below to determine which type of Distribution; Binomial, Geometric or Poisson, is being demonstrated. Then solve each problem, with a supporting process.
