Answer

# Answer: There is not enough information to determine whether this is an appropriate, random sample for the population in this scenario. # Brief Explanations: To assess sample - appropriateness, we need to know more about the migraine - suffering population. Just knowing that volunteers are randomly selected without age, gender, or race restrictions isn't sufficient. We don't know if the sample characteristics match those of the overall population of migraine sufferers in terms of factors like frequency of migraines, co - existing conditions etc.
