In an often-used survey system, customers are asked to rate a company’s product between 0 and 11 points, inclusive. Customers who chose scores between 0 and 6 points, inclusive, are interpreted to be unhappy with the product. People who selected either the score 7 or 8 points are interpreted to feel neutrally about the product. And customers who chose scores between 9 and 11 points, inclusive, are interpreted to be happy with the product.
a. What real number is in the middle of the scores 0 through 11?
b. On the basis of your result to part (a), does it make sense that people who selected the scores 7 or 8 are interpreted to feel neutrally about the product? Explain.
c. In your opinion, what would be a better way to interpret the scores?
