4. In our Presidential poll, we will make a good guess about the weights based on the information about each poll. Let's assign Poll 1 a weight of 0.2 (or 20%) and Polls 2 and 3 each a weight of 0.4 (40%). The polls and weights are summarized in the table below. Use the two-step procedure to calculate the weighted average of the three polls. Poll Result (Pro-Smith) Weight Result x Weight Poll A 45% 0.2 Poll B 51% 0.4 Poll C 52% 0.4 Weighted Average: Total = 1.0 5. Compare your results in questions 2 and 4. a) Does the advice that you provide to the President change if you used a weighted average? b) Which should be more accurate - the average in #2 or the weighted average in #4
