The clarily and cut of a diamond are two of the four C's of diamond grading. (The other two are color and carat.) For a sample of diamonds, the accompanying table lists the clarity (related as internally flawless, IF, very very slightly included, VVS, very slightly included, VS, slightly included. Sl and included, I) for the two lowest ratings for cut, which are "good" and "fair". Complete parts a through c below. E Click the icon to view the table a. Find the conditional proportions for the five categories of clarity, given cut Clarity by Cut Clarity vs Cut IF SI Total Good 89 Fair 53 (Round to three decimal places as needed) b. Sketch (or create using software) a side-by-side (or stacked) bar graph that compares the two cuts on clarity. Summartze findings in a paragraph. Let the left bar for each clarity represent "good" cuts and the right bar represent fair" cuts. Choose the correct answer below. OA. OB.

On the right are raw test scores from a history test. a. Construct an ordered stem and leaf plot for the given data. b. Construct a grouped frequency table for these scores with intervals of​ 5, starting the first class at 55. c. Draw a histogram of the data. d. If a circle graph of the grouped data in​ (b) were​ drawn, how many degrees would be in the section representing the 55–59 ​interval? 55 61 72 80 94 61 71 79 72 74 77 79 88 83 89 86 88 81 86 82 80 97 92 94 94
