Ten percent of the world's population is left-handed. A researcher claims that left-handed individuals are more creative than those who aren't left-handed. In order to support his claim, he takes a sample of 900 artists and finds that 9% of them are left-handed. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p, wherep is the proportion of left-handed individuals in a random sample of 900. 0.09 (b) Find the standard deviation of p. (c) Compute an approximation for P(p 20.09), which is the probability that there will be 9% or more left-handed people in a random sample of 900. Round your answer to four decimal places.

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.
