For his statistics class, casey is statistically pooling the results of several studies into a single analysis. clearly, casey has been assigned to conduct a:

b

The correct option is B

Explanation:

Meta- analysis is the tool for the analysis of statistical which combine or merge the consequences of the multiple scientific studies. This analysis is  conducted when there are multiple scientific studies, with each and every individual study that reports, the evaluations which are expected to have the  degree of the error.

a) Baker's profit margin = 7.5%

b) No change on return on total assets

Explanation:

a) Assets Turnover = = 1.6 times

Return on total assets = = 12%

Then we have profit margin on sales = = = 7.5%

b) In case asset turnover declined to 2 times with profit margin of 6% then Return on total assets = Asset turnover ratio X Profit Margin

= 2 X 6% = 12%

Thus there is no change in that case on return on total investments.

a) Baker's profit margin = 7.5%

b) Thus there is no change in that case on return on total investments.
