Which of the following is closest to the average (arithmetic mean) of the 9 changes in the value of imports between consecutive years from 2000 to
2009 ?
It mentions the average of the 9
changes in the imports values, so isn't the 9 differences to be taken into consideration? Then the average of these differences is asked, so we have to get the average of the differences in the import values between 2 consecutive years in the 2000 - 2009 decade period.
I am sorry, I am really confused because my interpretation of the question was this and I admit, this approach is much more convoluted and time consuming, but I am having a hard time in interpreting the question to get the answer specified, for the overall aggregate of the endpoint years 2000 and 2009, and not to consider the years within the range.
