In 2012 in the United States, most electricity was generated from coal (37%), natural gas (30%), or nuclear power plants (19%). Hydropower accounted for 7% of the total electricity produced; other renewable sources such as wind or solar p for 5%. Other nonrenewable sources (such as petroleum) made up the remaining 2%. Complete parts a through d below. a. Display the information in a bar graph. The bars, from left to right, represent coal, natural gas, nuclear power, hydropower, wind or solar, and other nonrenewable sources. Choose the correct graph below. OA. Q O B. Q 40 30- 20- LI 20- Q 10- 10- 0- 0- Electricity Source Electricity Source OC. Q Q 40 40 Q ..... 20- Electricity Source Electricity Source b. Which is easier to sketch relatively accurately, a pie chart or a bar chart? OA. A bar chart easier because the bars are always in decreasing order of category percentages, which makes comparisons of categories easier. OD.

Question
b. Which is easier to sketch relatively accurately, a pie chart or a bar chart? O A. A bar chart is easier because the bars are always in decreasing order of category percentages, which makes comparisons of categories easier. OB. A pie chart is easier because a pie chart has one shape (a circle), which is easier to graph more accurately than a bar graph, which has multiple shapes (multiple rectangles). OC. A pie chart is easier because estimating the sizes of the slices in a pie chart is easier than estimating the heights of the bars in a bar graph. O D. A bar chart is easier because sketching the exact percentages is more challenging in a pie chart. c. What is the advantage of using a graph to summarize the results instead of merely stating the percentages for each source? OA. A graph allows the viewer to easily see the center of the distribution. B. A graph allows the viewer to associate a shape with each category. O C. A graph allows the viewer to more easily judge the relative sizes of the percentages in each category. O D. A graph gives the viewer a better sense of the data because it associates a number with each category. d. Which is the modal category? The modal category is
