Basic Computation Suppose you have two independent samples with the first having sample size 15 and the second having sample size 16. Compute the mean and standard deviation of Ranks for the Rank-Sum test.

For Problems 6–14, please provide the following information.

(a) What is the level of significance? State the null and alternate hypotheses.

(b) Compute the sample test statistic. What is the sampling distribution? What conditions are necessary to use this distribution?

(c) Find the P-value of the sample test statistic.

(d) Conclude the test.

(e) Interpret the conclusion in the context of the application.
