In the previous lessons, you learned how to select confidence levels so that you will know the multipliers of standard errors. You learned how to estimate population proportions given observed frequencies obtained from surveys. Finally, you learned how to interpret results of estimations based on your confidence levels. Think of your answers to the following questions. 1. Describe the Four-Step Procedure in determining estimates of population proportions. What modifications do you suggest? 2. Are results of poll surveys important in real life? 3. Why should poll surveys be subjected to statistical procedures?
