Question

A) A pharmaceutical company wants to study the effectiveness of a new drug in treating migraine
headaches. For its trial, it gathers randomly selected volunteers regardless of their age, gender, or race.
Is this an appropriate, random sample on which the pharmaceutical company can rely to draw its
conclusions? (1 point)
There is not enough information to determine whether this is an appropriate, random sample for the
population in this scenario.
Yes, this is an appropriate, random sample.
No, this is not an appropriate, random sample. The company should only run the trial on female volunteers
because migraine headaches are more common in women.
No, this is not an appropriate, random sample. The company should only run the trial on volunteers age 50
and older.

Answer 1

Yes, this is an appropriate, random sample.

Reason: Randomly selecting volunteers regardless of age, gender, or race helps produce a sample representative of the population of migraine sufferers; restricting the trial to only women or only older adults would bias results.
