Test scores from a large calculus class of 400 are shown in the accompanying histogram. Complete parts a and b below. Click the icon to view the histogram. a) Describe the distribution of scores. What might account for this shape? What is the shape of the distribution? O A. Uniform O B. Unimodal and symmetric with a mode around 70 O C. Bimodal with modes around 60 and 80 O D. Unimodal and skewed right with a mode around 80 - X Histogram What might account for this shape? The shape is because 100- b) Why might both the mean and median score be misleading as a summary of the center? 80- O A. Because the distribution is skewed left, the mean does not tell much about a typical score. Because the distribution is unimodal, the median is not useful, either. O B. Because the distribution is skewed right, the mean does not tell much about a typical score. Because the distribution is unimodal, the median is not useful, either. 60 # of students O C. Because the distribution is bimodal, neither the mean nor the median tells much about a typical score. Reporting the modes would be more useful. 40- O D. Because the distribution is symmetric, the median does not tell much about a typical score. Because the distribution is unimodal, the mean is not useful, either. 20- 50 60 70 80 90 100 Print Done
