This set of question deals with advertising revenue and expense data of 30 publications. The focus here is more on two particular columns: ad revenue per reader and cost per impression (CPM) for 2006.
The first question examines the growth rate of a specific periodical between 2005 and 2006. This involves simply comparing the revenue data for these two years.
The second and third questions deal more with the metrics mentioned above. One asks you to compare the two values for each of the 30 companies and make an overall assessment about whether at least two-thirds of the companies listed show a positive ad revenue per radio to cost per impression ratio.
The other one makes a sweeping statement about the company that has the largest readership. Well, to find the company with the largest readership, you must first sort the data by the 2006 total readers. Then compare the ratio and see if any other company comes anywhere close.
