4.4 Everyday Application: Rating Films on a Numerical Scale. Assume that you and a friend often go to the cinema and afterwards assign a rating ranging from 0 to 10 to the film you have just seen.

A. Suppose you go to see a double feature, first Terminator Genisys and an adaptation of Jane Austen’s Emma. You rate Terminator Genisys as an 8 and Emma as a 2, and your friend rates Terminator Genisys a 5 and Emma a 4.

a. Do you and your friend agree on which film is better?

b. How would your answer change if your friend’s ratings had been reversed?

c. Can you tell for sure whether you liked Terminator Genisys more than your friend did?

d. Assume you both argue about your rankings. True or False: It makes little sense for you to argue if you both rank one film higher than the other even if you assign very different numbers
