Acell phone company wants to determine the average amount of data that their smart phone customers use each month. which group would best represent a sample of the population?
a. one thousand of their customers with the most expensive monthly plans
b. one thousand of their customers who most recently signed up with the company
c. one thousand of their customers with a current smart phone data plan
d. one thousand of their customers who called in for technical support

The correct answer to the question "A cell phone company wants to determine the average amount of data that their smart phone customers use each month. Which group would best represent a sample of the population?" is "one thousand of their customers with a current smart phone data plan" This is because drawing a sample from their customers with the most expensive monthly plans will give a biased data as to the average amount of data that ther smart phne customers use each month, as the data will be biased towards the expensive customers. Drawing a sample from their customers who recently signed up to the company and their customers who called in for technical support will not give adequate distribution for the required data as the new customers has not been using their data and data on the average use of data cannot be generated from them.
