Consider the random variable x, where x is the number of dots after rolling a die. Make a sketch of the probability distribution of this variable. What is the expected value of x?
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.
1. Consider the random variable x, where x is the number of dots after rolling a die. Make a sketch of the
2. Now consider the random variable that is the average number of dots after four Is this variable
3. Suppose we changed the definition to the average number of dots after forty Would this variable be normally distributed? Explain.
