You conjecture that the percentage of brown-eyed people in a large population is 15%. To test your conjecture, you get 20 random volunteers and check their eye color. Let B be the number of brown-eyed people in the sample. For applicable questions fill in the BLANK a. The random variable B has a distribution is (BLANK) with parameters (BLANK) b. The expected value of B is (BLANK) c. Calculate probability that B is greater than or equal to 8. d. Suppose you and 8 brown-eyed people in your random sample of 20. What do you think about your conjecture that 15% of the population is brown-eyed? Explain your reasoning.
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.
