Consider the experiment of rolling a pair of six-sided dice. Suppose that we are interested in the sum of the face values showing on the dice. a. How many sample points are possible? (Hint: Use the counting rule for multiple-step experiments.) b. Select the sample points. Numbers from the left side of the boxes are the face values showing on the first dice. Numbers from above the boxes are the face values showing on the second dice. Numbers inside the boxes are the total for both. 1.

3 1 point Which of the following statements is TRUE about sample size? Sample size is only important in observation research, not experimental research. A large sample size decreases the likelihood that the results of your experiment will be influenced by random Sample size is not that important. It is more important to test multiple variables to have a strong experiment. A small sample size decreases the likelihood that the results of your experiment will be influenced by random
