Assume a binomial probability distribution has p = .60 and n = 200.a. what are the mean and standard deviation?b. Is this situation one in which binomial probabilities can be approximated by thenormal probability distribution? Explain.c. what is the probability of 100 to 110 successes?d. what is the probability of 130 or more successes?e. what is the advantage of using the normal probability distribution to approximate thebinomial probabilities? Use part (d) to explain the advantage.
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.
