The US Department of Health and Human Services wants to know whether the national healthcare system is achieving its goals in Vi
rginia. 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? (4 points) Part B: 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. (6 points) (10 points)
A: The population of Virginia is the population, and the sample is the 65,439 people who were interviewed for the survey.
B: I think that these approximations are close the that of the entire population. This is because the surveyor randomly interviewed people in the population to create the sample. This means that there is no apparent bias in the experiment, which means that it is probable that the sample reflects the population
Ur answer is 6 (20+20+20+20+20+20+21+21+21+21+21+21+21+21+21+21+21+21=372) and they need at least 362 hope this helps I'm pretty sure this is right sorry if it's wrong but it seems right to me
