Question
Searc Po NO For Numbers 20 to 22: Risa, a public health advocate, intends to evaluate the efficiency of a training module on HIV awareness by administering pre- and post-test questionnaires to 30 randomly selected individuals before and after the training. She claims that the training module is not effective in increasing the posttest scores (i.e., posttest score <= pretest score) and intends to revise the module once data provides sufficient evidence to do so. The data summary are as follows: Test Mean (X) Median (M) A. HD SO Mean Difference (d) Pretest Scores 11 12 Posttest Scores 13 13 Let difference - posttest score - pretest score Note: Not all assumptions for parametric testing were satisfied. 2 20.
