Final answer:
The sampling distribution of the proportion of primary care doctors who think their patients receive unnecessary medical care can be modeled using the binomial distribution.
Step-by-step explanation:
The sampling distribution of the proportion of primary care doctors who think their patients receive unnecessary medical care can be modeled using the binomial distribution. In this case, the population would be all primary care doctors, and the parameter of interest would be the proportion of primary care doctors who think their patients receive unnecessary medical care.
The sample would be a subset of primary care doctors that are randomly selected. The statistic would be the proportion of primary care doctors in the sample who think their patients receive unnecessary medical care.
By collecting data from multiple samples, we can construct a sampling distribution, which would show the distribution of the sample proportions.
