Question

Colleen Waite director of general Canadian sales, is concerned by a downward sales trend, specifically their customer base is stable at 2200, but they are purchasing less each year. She orders her staff to search for causes of the downward trend by selecting a focus group of 50 customers.

1. The focus group of 50 customers represents a sample.

2. The focus group of 50 customers represents a population

3.The focus group of 50 customers represents a inferential statistic.

4. The focus group of 50 customers represents a census.

Answer 1

The focus group of 50 customers is a subset of entire population

total number of customers is the population in this case

we know that the subset of population is known as the sample

This means that he set of selected customer, i.e. focus group of 50 customers is the sample in this case.

It is neither population nor census because population or census represents a large group.

it is not inferential statistics because there is no prediction made using the sample data

therefore, option A is correct
