8) Ninety-eight college students were randomly assigned to one of two experimental conditions: rudeness condition (where students were berated by a facilitator for being irresponsible and unprofessional) and control group (no facilitator comments). Each student then wrote down as many uses for a brick as possible in 5 minutes. The data are shown in the accompanying table.

9) Suppose you wish to compare two treatments, A and B, on the basis of independent random samples of 15 observations selected from each of the two populations. If T1=165, do the data provide sufficient evidence to indicate that distribution A is shifted to the left of distribution B? Test, using =0.05.
