The August 2008 edition of Academy of Management Journal featured an investigation of the performance and timing of corporate acquisitions. The investigation discovered that in a random sample of 2778 firms, 748 announced one or more acquisitions during the year 2000. Does the sample provide sufficient evidence to indicate that the true percentage of all firms that announced one or more acquisitions during the year 2000 is less than 30%? Test to a level of significance of 0.05. The most appropriate hypothesis test to use for this scenario is: O A) z - test for single population mean (B) t - test for single sample O C) z - test for single sample O D) t - test for single population mean OE) z test for single population proportion
