The average price of a college math textbook is $171 and the standard deviation is $23. Suppose that 6 textbooks are randomly chosen. Round all answers to 4 decimal places where possible. Find the 95th percentile for an individual textbook price. (round to the nearest cent) $ For part b), is the assumption that the distribution is normal necessary? Yes or No
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.
