o one thousand of their customers with the most expensive monthly plans
o one thousand of their customers who most recently signed up with the company
o one thousand of their customers with a current smart phone data plan
o one thousand of their customers who called in for technical support

Explanation:

To find the average data - usage of smartphone customers, the sample should be representative of all smartphone customers. Customers with the most expensive plans may use more data than average, recent sign - ups may have different usage patterns, and those who called for technical support may not be a typical group. Customers with a current smartphone data plan are a more general and representative group of all smartphone customers.

one thousand of their customers with a current smart phone data plan
