Question

A survey is conducted to determine the most common reason people own a cell phone. A company sent out a survey to customers between the ages of 20 and 30. Based on the responses, the company concluded that people own a cell phone for messaging purposes. Is this conclusion valid?(1 point)

A. No, because the sample includes customers of too many different ages.
B. Yes, because the sample includes male and female customers.
C. No, because not all people who own a cell phone have the same probability of being selected. N
D.Yes, because the sample includes all customers between the ages of 20 and 30.

Answer 1

The correct answer is C. No, because not all people who own a cell phone have the same probability of being selected. The company only surveyed customers between the ages of 20 and 30, which may not represent the entire population of cell phone owners. It is possible that people outside of this age range have different reasons for owning a cell phone, so the conclusion may not be valid for the general population.
