There is considerable interest in understanding the availability of healthcare services across the United States. Hospital referral regions (HRRs) are defined geographic regions that represent local health markets - across the United States there are 306 HRRs. A recent study collected data on the rate of primary care physicians versus medical specialists across the 306 US HRRs (measured in the No. of physicians per 100,000 adults residing in the HRR). Use the data presented in the box plot (see below) to answer the following questions:
