Two random samples were taken to determine how often people in a community listen to the local radio station each month.
The first sample surveyed 15 people as they exited the bank of Main Street. The first sample found that the mean number of hours they listened to the radio each month was 20.
The second sample surveyed every sixth person as they exited the only local grocery store until 100 people were surveyed. The second sample found that the mean number of hours they listened to the radio each month was 12
Which statements are true? Check all that apply (multiple choice)
- the second sample is random
- the second sample is likely to be more representative of the population
- the first 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 will give a better representation because it is smaller.
- community members are more likely to listen to the radio station an average of 12 hours a month than 20 hours a month.
