About 10% of the general population is left-handed. However, about 25% of baseball players are left-handed. Suppose we take a random sample of 30 baseball players and let X = the number of left-handed players in the sample a. What is the probability that at most 8 are left-handed? b. What is the probability that 8 are left-handed? c. what is the probability that more than 12 are left-handed? d. What is the probability that at least 12 are left-handed?
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.
