# Question

Assume that we have two treatments (A and B) that produce quantitative results, and we have only two observations for treatment A and two observations for treatment B. We cannot use the test statistic given in this section because both sample sizes do not exceed 10.

a. Complete the accompanying table by listing the five roivs corresponding to the other five casts, and enter the corresponding rank sums for treatment A.

b. List the possible values of R and their corresponding probabilities.

c. Is it possible, at die 0.10 significance level, to reject the null hypothesis that there is no difference between treatments A and B? Explain.
