Consider the parameter(s) of interest in this study. • Label the appropriate parameter(s) of interest and write out what they are in plain English. Use proper statistical notation and an appropriate subscript to denote each population. Then, describe what the parameter(s) represent in terms of the study. • State the question of interest in terms of the parameters (using a mathematical relationship) and explain your reasoning.

![Vitamin E and the Risk of Prostate Cancer: Klien et al (2011) conducted the
following study to determine the effect of vitamin E and selenium treatment on
the risk of developing prostate cancer in healthy men. A total of 34,887 men
from different study sites in the United States, Canada, and Puerto Rico were
randomly selected. To be eligible to participate, the men had to take a rectal
examination that showed he was not suspicious of having prostate cancer and
be aged 50 years or older for black men and 55 years or older for all others.
Each man was randomly assigned to receive one of four treatments: selenium,
vitamin E, selenium and vitamin E together, or a placebo. The men were
followed up after 8 years to see if they had developed prostate cancer or not.
The main question of interest is to determine if the risk of developing prostate
cancer differs by the treatment taken. The data are summarized in the table
below:
