Explanation of Solution
The population is having all subjects about which want to collect information.
A sample is the part of the population of the information
It is observed that the sample is the 1000 people who signed a card saying they intended to quit. Smoking and who were selected at random. While the population then needs to quit smoking
A parameter is a descriptive measure for a population, where a statistic is a descriptive measure for a sample.
The 21% is based on the 1000 people in the sample and therefore 21% represents the sample proportion of the individuals who did not smoked since the past 6 months, which means that 21% represents a statistic.
The associating parameter is then the population proportion of individuals who did not smoked since the past 6 months.
Statistic:
Parameter:
