Trying to understand "Implied Population" in statistics
This is from the 12th edition of "Understandable Statistics" from Cengage Learning.
Chapter 1, Section 1, Question 8:
What is the average miles per gallon (mpg) for all new hybrid small cars? Using consumer reports, a random sample of such vehicles gave an average of 35.7 mpg.
(a) identify the variable: Miles per gallon
(b) is the variable qualitative of quantitative? Quantitative
(c) what is the implied population? The solution manual says that the implied population is gasoline mileage for all new small hybrid cars.
Unfortunately, the chapter never defines what an implied population is. To me it seems like the implied population is all small hybrid cars, and that the gas mileage of such cars is a variable (since it is a characteristic of the individual to be measured or observed).
Here are two vocab words from the 1.1:
Individuals are the people or objects included in the study A variable is a characteristic of the individual to be measured or observed.
