Patent infringement case. Refer to the Chance (Fall2002) description of a patent infringement case against Intel Corp., presented in Exercise. The zinc measurements for three locations listed in 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 following table and saved in the PATENT file.

a. Use a test (at α = .05) to compare the variation in zinc measurements for the text line with the corresponding variation for the intersection.
b. Use a test (at α = .05) to compare the variation in zinc measurements for the witness line with the corresponding variation for the intersection.
c. From your results in 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?
