Explanation of Solution

Given information:

Year	Trade deficit (in billions of dollars)
$1998$	$230$
$1999$	$329$
$2000$	$436$
$2001$	$412$
$2002$	$468$
$2003$	$532$
$2004$	$655$
$2005$	$772$
$2006$	$828$
$2007$	$809$
$2008$	$816$
$2009$	$504$
$2010$	$635$
$2011$	$725$
$2012$	$731$
$2013$	$689$

Graph:

  

Interpretation:

The above graph shows the trade deficits (the differences between imports and exports) of the United States from $1998$ through $2013$ .

(b).

To determine

To explain:

Brief statement describing the graph reveals.

Answer to Problem 26E

From the year $1998$ to $2000$ increased at constant rate then after $2008$ sudden decreased at constant rate and then again slight increased in rate after year $2009$ .

Explanation of Solution

Given information:

Year	Trade deficit (in billions of dollars)
$1998$	$230$
$1999$	$329$
$2000$	$436$
$2001$	$412$
$2002$	$468$
$2003$	$532$
$2004$	$655$
$2005$	$772$
$2006$	$828$
$2007$	$809$
$2008$	$816$
$2009$	$504$
$2010$	$635$
$2011$	$725$
$2012$	$731$
$2013$	$689$

Result obtained from part (a) that is line graph of the given data is as below:

  

From the above line graph it is observed that, trade deficits (the differences between imports and exports) of the United States from $1998$ to $2000$ increased at constant rate.

After year $2000$ to $2008$ trade deficits (the differences between imports and exports) of the United States slightly increases at different rates and then after $2008$ sudden decreased at constant rate and then again slight increased in rate after year $2009$ .
