8. An analyst is comparing data collected from randomly assigned test sub- jects who used two different types of hand cream (designated I and II), each for a period of six months. The subjects used one type of cream on one hand and the second on the other and reported a "softness" factor on a scale of 1 to 10 for each hand. What steps should the analyst take to determine which cream is more effective? (A) Calculate the mean difference between the right-hand results and the left-hand results, then carry out a one-sample z-test. (B) Calculate the difference in means between the right-hand results and the left-hand results, then carry out a two-sample z-test. (C) Calculate the mean difference between the right-hand results and the left-hand results, then carry out a one-sample t-test. (D) Calculate the difference in means between the right-hand results and the left-hand results, then carry out a two-sample t-test.
