Answer:
Population and Sample
Step-by-step explanation:
The state of Mississippi is the population
The randomly selected resident is the sample
Population Belt Use: 60%
Population No-belt Use: 40%
Sample (selected resident's) Seat-belt Use = Y
Note: the question doesn't state or ask whether Y is positive (use of seat belt) or negative (no use of seat belt).
How does the standard deviation of X compare with the standard deviation of Y?
X is the population standard deviation of seat belt use from the mean value of seat belt use WHILE Y is the sample standard deviation of seat belt use from the mean value (of all persons in the sample) of seat belt use.
