Power Moves 1 Copyright © 2026 Pearson Education, Inc. Power Moves An international environmental organization is researching how households in different countries approach energy conservation. To better understand behavioral trends, they surveyed 1,000 households from two countries, which they called Elaria and Austara in their report. The focus of the research was on two variables: country (Elaria or Austara) and whether or not each household actively monitors energy consumption (Yes or No). Data summary: ● 55% of the surveyed households are from Elaria, 45% from Austara. ● In Elaria, 80% of households actively monitor their energy usage. ● In Austara, 65% of households actively monitor their energy usage. The organization wants to use the data to assess where educational campaigns about sustainable energy practices might be most effective. 1. Draw a tree diagram representing the distribution of households by country and energy monitoring status. 2. Complete the two-way frequency table.
