Answer 1

Population: 21 million; parameter: 57%; sample: 85,349; statistic: 72%.

Step-by-step explanation:

The population is the entire group being studied, which in this case is all the residents of Florida, with a total population of 21 million.

The parameter is a numerical summary of the population, which in this case is the proportion of residents who visit a doctor annually and is stated as 57% in the problem.

The sample is a subset of the population that is selected for study, which in this case is the 85,349 adults surveyed by the surveyor.

The statistic is a numerical summary of the sample, which in this case is the proportion of adults in the sample who stated that they have visited a doctor within the past year and is stated as 72% in the problem.
