Two random samples were done to determine how often people in a community go to the dentist. The first sample surveyed 10 people as they entered their workplaces. The first sample found that the mean time between visits to the dentist was 7.5 months. The second sample surveyed 50 people as they entered the local grocery store. The second sample found that the mean time between visits to the dentist was 18.1 months. Which statements are true? Check all that apply. The first sample is likely to be more representative of the population. The second sample is likely to be more representative of the population. The second sample will give a better representation because it is larger. The first sample is not biased. Community members probably visit the dentist about once every 18 months.
