A business journal investigation of the performance and timing of corporate acquisitions discovered that in a random sample of 2,893 firms, 759 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 28%? Use a = 0.05 to make your decision. What are the hypotheses for this test? O B. Ho: p= 0.28 H: p>0.28 O A. Ho: p= 0.28 H3: p#0.28 O C. Ho: p 0.28 H3: p= 0.28 O D. Ho: p>0.28 H: ps0.28 O F. Ho: p<0.28 E. Ho: p=0.28 Ha: p<0.28 H: p = 0.28 What is the rejection region? Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to three decimal places as needed.) O A. z< O B. or z>

H3: p= 0.28
O D. Ho: p>0.28
H: ps0.28
OF. Ho: p<0.28
E. Ho: p=0.28
Ha: p<0.28
H: p= 0.28
What is the rejection region? Select the correct choice below and fill in the answer box(es) to complete your choice.
