12.11. A random sample of size n from an exponential population is used to test the null hypothesis 0 = Өо 01 > O0. Use the Neyman-Pearson lemma to find the most powerful criti- cal region of size a, and use the result of Example 7.16 on %3D against the alternative hypothesis 0 = page 222 to indicate how to evaluate the constant.
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.
Disregard the last part of the question which says "use the result of Example 7.16 on page 222 to indicate how to evaluate the constant" .
