Suppose that it is known that 10 percent of a certain population is color blind. If a random sample of 20 people is drawn from this population, answer the following: (a) What is the probability of five or fewer are color blind? Also, What is the probability between 6 and 9, inclusive will be color blind? How many people on average will be color blind in the sample? Additionaly, What is the standard deviation of the number of people who will be color blind in the sample?
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.
Suppose that it is known that 10 percent of a certain population is color blind. If a random sample of 20 people is drawn from this population, answer the following:
-

-
How many people on average will be color blind in the sample? Additionaly, What is the standard deviation of the number of people who will be color blind in the sample?
