Answer 1

Answer:

The population consists of the 201 people who bought tires last month.

The sample consists of the 51 people who responded.

Step-by-step explanation:

In statistical analysis, the population is a set of all values that can be considered for an experiment. It is a set of observations from which a sample is selected. The sample is a subset of the population.

In this case, it is provided that a tire company sends an email survey to all customers who purchase new tires each month.

The number of tires sold last month was N = 201.

The email survey was sent to 100 of these 201 people and 51 responded.

In this case, since the survey is done every month, the population consists of all the people who bought tires the previous month.

So, the population consists of the 201 people who bought tires last month.

The number of people who responded was, n = 51.

The sample consists of these 51 people because the data from these 51 people would be used to conduct and draw conclusion about the survey.

So, the sample consists of the 51 people who responded.
