Question

For Exercises 1 to 4, identify the population, the parameter, the sample, and the statistic in each setting.

Gas prices How much do gasoline prices vary in a large city? To find out, a reporter records the price per gallon of regular unleaded gasoline at a random sample of $10$gas stations in the city on the same day. The range (maximum-minimum) of the prices in the sample is $25$cents

Short answer

All stations of gasoline are the population.

$10$selected gas stations are the sample.

A topic that is being investigated is the parameter.

Range of the price which is 25 cents is the statistic.

Step-by-step solution

Given Information

What amount do gas costs differ in a for each gallon of customary unleaded fuel at an irregular example of $10$corner stores in the city around the same time. The range (most extreme - least) of the costs in the example is $25$pennies.

Explanation

The individuals that are studied are considered as the population. Here, all stations of gasoline are the population.

A sample is the subpart of the population that is studied to get the details about the population. Here, $10$selected gas stations are the sample.

The parameter is the measure of the original population. Here, a topic that is being investigated is the parameter.

Statistic is the measure of the sample. Here, range of the price which is $25$cents is the statistic.
