The US Department of Health and Human Services wants to know whether the healthcare system is achieving its goals in Virginia. Much information about healthcare comes from patient records, but that source doesn't allow us to compare people who use health services with those who don't. Therefore, the US Department of Health and Human Services conducted the Virginia Health Survey, which was used to interview a random sample of 65,439 people who live in the state of Virginia. Part A: What is the population for this sample survey? What is the sample? The survey found that 71% of males and 88% of females in the sample had visited a general practitioner at least once during the past year. Do you think these estimates are close to the truth about the entire population? Explain.
