To Explain: the about parameter, statistics etc.
Explanation of Solution
The population is having all individual about which want is collecting the information.
A sample is the part of the population of the information was actually collected.
It is observed that the sample is the 60,000 arbitrary selected U.S. adults, where the population then needs to be all U.S. adults A parameter is a descriptive measure for a population, where a statistic is a descriptive measure for a sample.
The 4.9% is based on the 60,000 adults in the sample and therefore 4.9% represents the sample proportion of U.S. adults who were unemployed, which means that 4.9% represents a statistic.
The associating parameter is then the population proportion of U.S. adults who were unemployed..
