Question

Determine the null hypothesis and the alternate hypothesis: ************************** 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%

Answer 1

Following are answer to these question:

`\LARGE H_0: p = 30 \%\\\\\LARGE H_A: p < 30 \%`

Explanation:

Even though researchers try and check whether the real percentage of all companies announcing one or more purchases that year 2000 is less than 30%, the invariant hypothesis therefore becomes as follows:

`\LARGE H_0: p = 30 \%\\\\\LARGE H_A: p < 30 \%`
