For the following assignment, use the Rank Correlation given
below. Use a rank correlation coefficient to test for a correlation between two
variables.

  1. Use a significance level of
    a=0.05.

The new health care program in the United States makes
provisions for capitation programs where health care insurers work with
clinical facilities to perform risk analysis of patients to determine the cost
of providing care. The following assignment might be used to assess how much a
person smokes.

When nicotine is absorbed by the body, cotinine is produced. A
measurement of cotinine in the body is therefore a good indicator of how much a
person smokes. The reported number of cigarettes smoked per day and the
measured amounts of cotinine (in ng/ml) are provided. (The values are from
randomly selected subjects in a National Health Examination Survey.) Is there a
significant linear correlation? How would you measure the cotinine level in the
body? Explain the result.

Refer to the “Rank Correlation Table.”

APA format is not required, but solid academic writing is
expected.
