We were unable to transcribe this imageThese scores would be easier to visualize and interpret if they were graphed as a histogram. To do that, we first need to group them into class intervals and present them as a frequency distribution of grouped scores Table 2 divides the range of these 25 schools' academic performance into ten intervals. Based on the information provided in Table 1, use the dropdown menus to fill in the rest of Table 2 and complete...
