Final answer:
To find the average cost of a two-day stay in a hospital in Massachusetts, survey 100 hospitals using simple random sampling. If your wait time in the emergency room is in the 82nd percentile, it means your wait time is shorter than 82% of other patients.
Step-by-step explanation:
In order to find the average cost of a two-day stay in a hospital in Massachusetts, you would need to survey 100 hospitals across the state using simple random sampling. This means that you would randomly select 100 hospitals and collect data on their costs for a two-day stay. You would then calculate the mean (average) of these costs to determine the average cost of a two-day stay in a hospital in Massachusetts.
If you learn that your wait time in the emergency room was in the 82nd percentile of all wait times, it means that your wait time was longer than 82% of other patients' wait times. In this case, waiting 90 minutes before seeing a doctor is considered relatively good compared to other wait times, as it is shorter than 82% of other wait times.
