Hypothesis:  The mean number of addicts who have gone through rehab
will be found to have long-term sobriety and thus we can infer a
linear relationship between the  two variables.

Out of 20 clients that had been through rehab sobriety times were:  5
= one year; 7 = two years; 2 = three years; 1 = five years; 4 = six
years; and 1 = seven years.  Of 10 clients that had not been through
rehab sobriety times were:  2 = ten years; 3 = sixteen years; 2 =
twenty-five years; 1 = twenty-seven years; 1 = thirty years; and 1 =
thirty-seven years.
