Dr. Gill wants to arrange the answers to a true-false exam in random order. The answers in order of occurrence are shown below. T T T T F F F F F T T T T F F F F F F T T T T T T Test the sequence for randomness using α = 0.05. (b) Give α. (c) Find the sample test statistic. (d) For the sign test, rank-sum test, and Spearman correlation coefficient test, find the P-value of the sample test statistic. For the runs test of randomness, find the critical values from Table 10 of Appendix II. c1 c2
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.
