Chapter 8, Problem 84E(choose chapter or problem)
Patent infringement case. Refer to the Chance (Fall 2002) description of a patent infringement case against Intel Corp., Exercise 8.19 (p. 435). The zinc measurements for three locations on the original inventor’s notebook— on a text line, on a witness line, and on the intersection of the witness and text line—are reproduced in the table.
a. Use a test (at a = .05) to compare the variation in zinc measurements for the text line with the corresponding variation for the intersection.
b. Use a test (at a = .05) to compare the variation in zinc measurements for the witness line with the corresponding variation for the intersection.
c. From the results, parts a and b, what can you infer about the variation in zinc measurements at the three notebook locations?
d. What assumptions are required for the inferences to be valid? Are they reasonably satisfied? (You checked these assumptions when answering Exercise 8.19d.)
