QUESTION: FAIR OR NOT? Choose a letter and Explain why that corresponds to the best answer. Target Corporation is interested in how their customers feel about self-checkout service. They have an optional survey at the end of their receipt for those customers who have purchased items at Target. Target collects survey data from more than 7200 customers and discovers that 66% of Target customers like using self-checkout. What can Target conclude?

A. Because the sample size is large (more than 7200), it is reasonable to conclude that 66% of the customers like using the self-checkout line.

B. The result is surprising but reasonable because people view using the self-checkout line as convenient as the regular checkout line.

C. The survey is biased by voluntary response and probably overestimates the percentage of those who like using the self-checkout line.
