reviewers is concerned about the external validity of her study, which of the
following is the most important aspect of Dr. Guidry's study to consider?
the number of significant findings
the random sampling technique used to recruit the participants
the number of people in the sample

The University of Michigan Health and Retirement Study (HRS) surveys more than 22,000 Americans over the age of 50
every two years. A subsample of the HRS participated in an Internet-based survey that collected information on a number of
topical areas, including health (physical and mental health behaviors), psychosocial items, economics (income, assets,
expectations, and consumption), and retirement. Two of the questions asked were: "Would you say your health is excellent,
very good, good, fair, or poor?" and “Do you smoke cigarettes now?" Here is the two-way table that summarizes the answers
on these two questions:

A study was conducted to explore the prevalence and impact of sleep problems on various aspects of people's lives. Staff from a university in Melbourne, Australia were invited to complete a questionnaire containing questions about their sleep behaviour (e.g. hours slept per night), sleep problems (e.g. difficulty getting to sleep) and the impact that these problems have on aspects of their lives (work, driving, relationships). The sample consisted of 271 respondents (55% female, 45% male) ranging in age from 18 to 84 years (M=43.9yrs). A student researcher is interested in examining whether the participants in the study sleep for 8 hours a night, the recommended average for adults.
