Suppose you want to know how Arizona workers age 16 or older travel to work. To estimate the percentage of people who use the different modes of travel, you take a sample containing 500 Arizona workers age 16 or older. State the individual, variable, population, sample, parameter, and statistic.

The individual for this case represent the Arizona worker age 16 or older

The variable of interest on this case is the different modes of travel in the working people at Arizona age 16 or older

The population of interest represent all the Arizona workers age 16 or older

The sample represent the 500 Arizona workers age 16 or older selected from the population

The parameter of interest n this case is the proportion of people who use different moes of travel denoted by for an specific mode of travel i, and the proportion can be expressed as a % multipliying by 100.

The statistic for this case would represent the estimated proportion calculated from the sample for an specific mode of travel i

Step-by-step explanation:

Previous concepts

A statistic is a numerical value "used to estimate the value of a population parameter".

A parameter is a numerical value that describe a characteristic of an entire population

Solution to the problem

The individual for this case represent the Arizona worker age 16 or older

The variable of interest on this case is the different modes of travel in the working people at Arizona age 16 or older

The population of interest represent all the Arizona workers age 16 or older

The sample represent the 500 Arizona workers age 16 or older selected from the population

The parameter of interest n this case is the proportion of people who use different moes of travel denoted by for an specific mode of travel i, and the proportion can be expressed as a % multipliying by 100.

The statistic for this case would represent the estimated proportion calculated from the sample for an specific mode of travel i

i think the answer is b
