The sample percentages vary across the random samples of doctors. Some samples have higher percentages, while others have lower percentages, reflecting the variability in the proportion of doctors who prescribe the medication.
The question is asking about the variability of sample percentages based on a simulation of 200 random samples of 50 doctors each. The provided frequency table shows the distribution of sample percentages, ranging from 0.30 to 0.80.
The frequencies indicate how many samples had a particular percentage. For example, 25 samples had a percentage of 0.30, 20 samples had a percentage of 0.40, and so on.
This information suggests that the sample percentages vary across the different random samples. Some samples may have higher percentages, while others may have lower percentages.
The variability in the sample percentages reflects the randomness of the sampling process and the variability in the proportion of doctors who prescribe the particular medication.
