    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 patients—all waiting liver transplants in the intensive care unit (ICU)—are reported in the accompanying table.
    Organ Bile
    Dysfunction Blood Level Age Apache Goris Blood
    Group (mg/dL) (years) Scale Scale SIRS Culture Infection
    Mild 1.22 54 21 6 No Positive No
    Mild 1.89 37 21 5 No Positive Yes
    Mild 0.58 59 19 5 No Negative No
    Mild 0.13 24 12 4 No Negative No
    Mild 2.21 39 7 3 No Negative No
    Mild 0.96 75 10 2 No Negative No
    Mild 0.54 40 23 9 Yes Positive No
    Mild 1.11 44 27 8 Yes Negative No
    Mild 2.81 51 26 10 Yes Positive No
    Mild 1.11 28 18 7 Yes Positive No

    Severe 0.44 58 25 8 Yes Positive Yes
    Severe 1.39 65 27 9 Yes Positive Yes

    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).
    e.) Develop a 100% Bar Chart for Blood Culture
    f.) Develop a Pie Chart for Infection

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

    Answer

    The number of class intervals can be calculated from 2k > n rule. Since 128=27 > 70, the number of class interval is fixed as 7.
