Solution Steps

To determine which study uses a population parameter, we need to identify if the data provided represents the entire population or just a sample. A population parameter is a value that represents a characteristic of the entire population, whereas a sample statistic is a value that represents a characteristic of a sample drawn from the population.

1. The average finish time for the Ironman, Kona was 11:32 for the 1883 finishers, with an average swim time of 1:14, an average bike time of 5:53, and an average run time of 4:14. (This represents the entire population of finishers in that event.)
2. In a study of 89 of the children diagnosed with cancer at Leeland Memorial Hospital, 70 children were cancer-free five years after their first diagnosis. (This is a sample of children diagnosed with cancer at the hospital.)
3. Lakeside Family Dentistry reported that 6 of the 15 patients who came in for a regular cleaning one day had at least one cavity. (This is a sample of patients who came in for a cleaning on a specific day.)
4. In the 1950s, Eugene Gilbert interviewed 3975 parents and found that 29% thought rock 'n' roll should be banned from their communities. (This is a sample of parents interviewed.)

The first scenario uses a population parameter because it includes data for all finishers of the Ironman, Kona event.

We have four scenarios of statistical studies. We need to determine which study uses a population parameter. A population parameter is a characteristic that describes an entire population, while a sample statistic describes a characteristic of a sample drawn from that population.

1. Ironman Finish Times: The average finish time for the Ironman, Kona was \( 11:32 \) for the \( 1883 \) finishers. This data represents all finishers of the event, indicating it is a population parameter.

2. Cancer Study: In a study of \( 89 \) children diagnosed with cancer, \( 70 \) were cancer-free after five years. This is a sample of children from a larger population of all children diagnosed with cancer, thus it is a sample statistic.

3. Dentistry Report: Lakeside Family Dentistry reported that \( 6 \) of the \( 15 \) patients had at least one cavity. This is also a sample from the population of all patients visiting the clinic, making it a sample statistic.

4. Rock 'n' Roll Survey: In the \( 1950s \), \( 3975 \) parents were interviewed, and \( 29\% \) thought rock 'n' roll should be banned. This represents a sample of parents, not the entire population, so it is a sample statistic.

The only scenario that uses a population parameter is the first one regarding the Ironman finish times, as it includes data for all finishers of that specific event.
