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.
