A surveyor randomly interviewed 34,572 people who live in Scotland to gather information on whether national healthcare is accomplishing its goals. Part A: What are the population and sample in this survey? (4 points)

Part B: The survey found that 70% of smokers and 87% of non-smokers visited a family doctor at least once in the past year. Do you think these approximations of the sample are close to approximations of the entire population? Explain. (6 points)

I NEED PART B

Part A

Here the entire population is the total number of people who live in Scotland and the sample considered in this survey is the randomly chosen 34,572 people.

Part B

The approximations made out of the sample cannot be considered same as that of the entire population. Because here, only a random sample of 34,572 is taken whereas the total population here is the people who live in the Scotland, which can be quite large sample. The patient details recorded are used for survey. So in the sample surveyed we do not have the data about the rest of the population. The approximations made out of the sample become same as that of the entire population only if the entire population number is near to the randomly collected sample.
