About 10% of the general population is left-handed. However, about 25% of baseball players are left-handed. a. Let X = the number of left-handers in a random sample of 25 people from the general population. State n and p. Find the expected number of left-handers and the standard deviation. b. let X = the number of left-handers in a random sample of 25 baseball players. State n and p. Find the expected number of left-handers and the standard deviation.
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.
