Chapter 10, Problem 10.50ACI

History of corporate acquisitions. Refer to the Academy of Management Journal (August 2008) investigation of the performance and timing of corporate acquisitions, Exercise 2.12 (p. 50). Data on the number of firms sampled and the number that announced one or more acquisitions during the years from 1980 to 2000 are saved in the accompanying file. Suppose you want to determine if the proportion of firms with acquisitions differed annually from 1990 to 2000, that is, you want to determine if year and acquisition status were dependent from 1990 to 2000.

a. Identify the two qualitative variables (and their respective categories) to be analyzed.

b. Set up the null and alternative hypotheses for the test.

c. Use the Minitab printout at the top of next page to conduct the test at α = .5.
