Use the 2k > n rule to prepare a Frequency Distribution of the above data set and then construct a Histogram, Frequency Polygon and Ogive.

Part 2: (30 Points) The following list contains the number of customers assisted by three financial advisors in a local bank over a 10-day period.

Financial Day
Advisor 1 2 3 4 5 6 7 8 9 10
Alan 41 36 30 26 23 22 23 20 17 18
Beth 33 31 35 29 32 32 30 29 34 27
Clair 22 24 25 26 31 35 35 37 38 39

Prepare: a.) Stem-and-Leaf Chart for Alan
b.) Ordered Array for Beth
c.) Box-and-Whisker Plot for Clair
d.) Pie Chart showing percentages for Alan, Beth and Clair
e.) Time Line (on one chart) for Alan, Beth and Clair
f.) 100% Bar Chart (on one chart) for Alan, Beth and Clair based on the company standard that financial advisors must assist at least 30 customers a day to be considered successful. (i.e., less than 30 is considered unsuccessful)

Part 3: (50 Points) Systematic Inflammatory response syndrome (SIRS) is a major problem for patients with disfunctioning organs. Medical researchers at the University of Pittsburgh (Journal of the American Medical Association, July 5, 1995) conducted a study of the incidents of SIRS in 22 patients with cirrhosis of the liver. The clinical characteristics of the 22 patientsâ€”all waiting liver transplants in the intensive care unit (ICU)â€”are reported in the accompanying table.

a.) Develop a Pareto Chart for the Organ Dysfunction Group.
b.) Draw a Box-and-Whisker Plot for the Bile Blood Level
c.) Construct a Stem-and-Leaf Chart for age.
d.) Develop a Scatter plot for the Goris Scale (x-axis) and the Apache Scale (y-axis).
