Suppose that χ2 follows a chi-square distribution with 16 degrees of freedom. Use the ALEKS calculator to answer the following. (a) Compute P≤χ225 . Round your answer to at least three decimal places. =P≤χ225 (b) Find k such that =P≥χ2k0.05 . Round your answer to at least two decimal places. =k
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.
