  1. A geologist employed by a ski resort measures the stability of a rock face near the lodge on a scale of 1 to 100, with 1 meaning it will collapse today, and 100 meaning it will last until the end of time. This particular rock face receives a 64. This is an example of a ______________.<\/li>\r\n \t

    1. A nurse in an intensive care unit measures the risk of superbug infection in the ward using a metric based on the percentage chance of a patient becoming ill with such an infection in a two week period of admission. Values range from 0-100%. The variable of superbug infection risk would best be described as ______________.<\/li>\r\n \t
    2. A nurse in an intensive care unit measures the risk of superbug infection in the ward by recording which types of fungi\/bacteria are present in each patient\u2019s screening upon discharge. The variable of superbug infection risk would best be described as ______________.<\/li>\r\n<\/ol>\r\nObjective: Apply techniques Grouped Frequency Table, Histogram, Describe Distribution Shape<\/em>\r\n

      1. A forensic psychologist measures 20 inmates in a prison on the Hare Psychopathy Checklist \u2013 Revised (PCL-R). The results are as follows: 32, 40, 18, 22, 38, 25, 15, 19, 36, 33, 10, 24, 22, 18, 37, 33, 27, 25, 40, 26. Create a grouped frequency table using value ranges that begin with 1s or 6s and results in 4 rows. Create a histogram using the same ranges. Describe the shape of the smoothed distribution in terms of both symmetry and peaks. The percentage of inmates that scored in the 31-40 range (and thus qualified as \u201cPsychopaths\u201d) is ______________.<\/li>\r\n \t
