The department of health in the united kingdom wants to know whether the healthcare system is achieving its goals in scotland. 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 department of health conducted the scotland health survey, which was used to interview a random sample of 34,572 people who live in scotland. part a: what is the population for this sample survey? what is the sample? (4 points) part b: the survey found that 70% of males and 87% 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)
