The United Nations stores data about the kilowatt-hours of wind power produced around the world. The following data set gives information on the United States for 25 years, from 1990 to 2014, in units of million kilowatt-hours.

Using a calculator or statistical software, find the linear equation of the first 11 years of data, from 1990 to 2000. 

How close does your calculated value of a 2001 prediction match the actual value as found in the data set? Round the percent to the nearest ten.
